Let’s start with the Draconids, which will reach their peak on October 9. With a Zenithal Hourly Rate (ZHR) of 10, this meteor shower is best observed in the evening hours. The Northern Hemisphere is more likely to enjoy the Draconids, while observers from the Southern Hemisphere might also catch a glimpse. The radiant, located in the constellation Draco, will rise in the evening sky, offering ample time for observation before the Moon rises later in the night.

Next up is the Orionids, set to be the most spectacular meteor shower of October. Peaking on October 22, this shower boasts a ZHR of 20 and is visible from anywhere on Earth. The First Quarter Moon will set around midnight, allowing for optimal viewing conditions. Known for their fast meteors and occasional bright fireballs, the Orionids are among the most beautiful meteor showers of the year.

In addition to these major showers, there are several minor meteor showers to look out for. On October 6, the October Camelopardalids will peak with a ZHR of 5, visible primarily from the Northern Hemisphere. The Delta Aurigids, with a ZHR of 2, will peak on October 11, while the Southern Taurids will have an early peak on October 13, followed by another peak on November 5. Finally, the Epsilon Geminids will reach their peak on October 18 with a ZHR of 3.

Each meteor shower has its unique characteristics and viewing opportunities. Whether you’re a seasoned stargazer or a photography enthusiast, these meteor showers offer a chance to witness nature’s mesmerizing spectacle. So mark your calendars, find a dark spot away from city lights, and prepare to be dazzled by the shooting stars of October 2023.

How to See Comet C/2023 A3 (Tsuchinshan-ATLAS) Tonight

Published

on

Hello fellow star gazers! 🌌 As an amateur astronomer and night sky enthusiast, I’m beyond excited to share that Comet C/2023 A3 (Tsuchinshan-ATLAS)—the most talked-about comet of 2024—is already gracing our skies! Right now, observers in the Southern Hemisphere are enjoying its brilliance, and it won’t be long before us in the Northern Hemisphere can join in on the excitement. So grab your binoculars and stargazing apps, because tonight could be your chance to catch this spectacular cosmic visitor!

What Makes C/2023 A3 (Tsuchinshan-ATLAS) So Special?

Let’s dive into why this comet is capturing the imagination of so many. To begin with, C/2023 A3 is expected to be exceptionally bright. While its future brightness is still a work in progress (thanks to the unpredictable nature of comets), most sources agree that we might see it with the naked eye. If we’re lucky, it could even outshine the iconic Comet NEOWISE from the summer of 2020. Hasn’t it been a while since we’ve seen a comet this remarkable?

Additionally, C/2023 A3 is anticipated to develop an awe-inspiring cometary tail. After it swings past the Sun at a distance similar to Mercury’s orbit, the heat will cause its icy core to evaporate dramatically, leading to the formation of an impressive tail made of dust and gas. If history teaches us anything, it’s that comets heated by the Sun often exhibit the most striking tails.

For those of us in the Northern Hemisphere, this is particularly exciting! The last time we saw such a bright comet visible from northern latitudes was during the 1997 spectacle of Comet Hale-Bopp.

Is C/2023 A3 (Tsuchinshan-ATLAS) Visible Now?

Good news for those in the Southern Hemisphere! Currently, C/2023 A3 is visible in the mornings, appearing low in the eastern sky just before sunrise. With a current magnitude of about 2.6, it’s brighter than anticipated and continues to brighten daily.

If you’re in the Northern Hemisphere, the comet is a bit more challenging to see due to the Sun’s brightness; however, it’ll start becoming visible in early October.

Visibility Forecast: What Lies Ahead

Let’s paint a picture of what to expect in the coming weeks:

  • September 27 – October 2: This is when the comet reaches perihelion, appearing in the early morning sky.
  • October 10-12: The comet will become more visible in the evening, shortly after sunset, in the constellation Virgo. These dates are critical as it will be at its brightest around October 12, making it easier to see with the naked eye.
  • October 15-31: The comet will fade but will still be visible with binoculars and telescopes.

The best time for observation is likely from October 10-12, just after sunset. So get out there—don’t miss the chance to witness this celestial wonder!

Tips for Photographing C/2023 A3 (Tsuchinshan-ATLAS)

If you’re an aspiring astrophotographer like me and you want to capture this comet on film, consider following these steps:

  1. Gear up: Have a DSLR or mirrorless camera, sturdy tripod, and a wide-angle or zoom lens ready.
  2. Camera Settings: Use manual mode with an ISO setting between 400 and 800, and a wide aperture of f/2.8 to f/4 to let in enough light.
  3. Location Matters: Pick a dark spot far from city lights. Star Walk 2 can help you find the comet’s exact location.
  4. Take Multiple Shots: For detailed images, take a series of photographs and use software like DeepSkyStacker for stacking.
  5. Post-processing: Tools like Photoshop will help refine your final image.

The Journey Ahead: What’s Next for C/2023 A3?

As we all wait in eager anticipation, it’s worth noting that C/2023 A3 (Tsuchinshan-ATLAS) is on a long journey. It completes one orbit around the Sun roughly every 80,660 years! If you’re wondering what the future holds, after its approach in October, this comet will slowly fade from view and won’t return until the year 26,000.

To Wrap Up

Excitement is in the air as we prepare to welcome this spectacular comet! C/2023 A3 (Tsuchinshan-ATLAS) is already putting on a show for observers in the Southern Hemisphere, and soon it will light up the skies for us in the North. As we gear up for this enchanting astronomical event, don’t forget to download the Star Walk 2 app to help you navigate the night sky like a pro.

A new ‘guest star’ will appear in the sky in 2024 − a space scientist explains how nova events work and where to look

The nova explosion in T Coronae Borealis, visible from Earth in 2024, will be a unique celestial event, unlike the supernova of 1054.

Published

The stars aren’t fixed and unchanging, unlike what many ancient people thought. Once in a while, a star appears where there wasn’t one before, and then it fades away in a matter of days or weeks.

The earliest record of such a “guest star,” named so by ancient Chinese astronomers, is a star that suddenly appeared in skies around the world on July 4, 1054. It quickly brightened, becoming visible even during the day for the next 23 days.

Astronomers in Japan, China and the Middle East observed this event, as did the Anasazi in what is now New Mexico.

In the second half of 2024, a nova explosion in the star system called T Coronae Borealis, or T CrB, will once again be visible to people on Earth. T CrB will appear 1,500 times brighter than usual, but it won’t be as spectacular as the event in 1054.

I am a space scientist with a passion for teaching physics and astronomy. I love photographing the night sky and astronomical events, including eclipses, meteor showers and once-in-a-lifetime astronomical events such as the T CrB nova. T CrB will become, at best, the 50th brightest star in the night sky – brighter than only half the stars in the Big Dipper. It might take some effort to find, but if you have the time, you’ll witness a rare event.

What is a nova?

In 1572, the famous Danish astronomer Tycho Brahe observed a new star in the constellation Cassiopeia. After reporting the event in his work “De Nova Stella,” or “On the New Star,” astronomers came to associate the word nova with stellar explosions.

Stars, regardless of size, spend 90% of their lives fusing hydrogen into helium in their cores. How a star’s life ends, though, depends on the mass of the star. Very massive stars – those more than eight times the mass of our Sun – explode in dramatic supernova explosions, like the ones people observed in 1054 and 1572.

In lower mass stars, including our Sun, once the hydrogen in the core is exhausted, the star expands into what astronomers call a red giant. The red giant is hundreds of times its original size and more unstable. Eventually, all that is left is a white dwarf – an Earth-sized remnant made up of carbon and oxygen. White dwarves are a hundred thousand times denser than diamond. Unless they’re part of a binary star system, where two stars orbit each other, they slowly fade in brightness over billions of years and eventually disappear from sight.

T CrB is a binary star system – it’s made up of a red giant and a white dwarf, which orbit each other every 228 days at about half the distance between Earth and the Sun. The red giant is nearing the end of its life, so it has expanded dramatically, and it’s feeding material into a rotating disk of matter called an accretion disk, which surrounds the white dwarf.

Matter from the accretion disk, which is made mostly of hydrogen, spirals in and slowly accumulates on the surface of the white dwarf. Over time, this blanket of hydrogen becomes thicker and denser, until its temperature exceeds 18 million degrees Fahrenheit (10 million degrees Celsius).

A nova is a runaway thermonuclear reaction similar to the detonation of a hydrogen bomb. Once the accretion disk gets hot enough, a nova occurs where the hydrogen ignites, gets blown outward and emits bright light.

When will it occur?

Astronomers know of 10 recurrent novae – stars that have undergone nova explosions more than once. T CrB is the most famous of these. It erupts on average every 80 years.

Because T CrB is 2,630 light-years from Earth, it takes light 2,630 years to travel the distance from T CrB to Earth. The nova we will see later this year occurred over 2,000 years ago, but its light will be just reaching us later this year.

The accretion of hydrogen on the surface of the white dwarf is like sand in an 80-year hourglass. Each time a nova occurs and the hydrogen ignites, the white dwarf itself is unaffected, but the surface of the white dwarf is wiped clean of hydrogen. Soon after, hydrogen begins accreting on the surface of the white dwarf again: The hourglass flips, and the 80-year countdown to the next nova begins anew.

Careful observations during its past two novae in 1866 and 1946 showed that T CrB became slightly brighter about 10 years before the nova was visible from Earth. Then, it briefly dimmed. Although scientists aren’t sure what causes these brightness changes, this pattern has repeated, with a brightening in 2015 and a dimming in March 2023.

Based on these observations, scientists predict the nova will be visible to us sometime in 2024.

How bright will it be?

Astronomers use a magnitude system first devised by Hipparchus of Nicaea more than 2,100 years ago to classify the brightness of stars. In this system, a difference of 5 in magnitude signifies a change by a factor of 100 in brightness. The smaller the magnitude, the brighter the star.

In dark skies, the human eye can see stars as dim as magnitude 6. Ordinarily, the visible light we receive from T CrB comes entirely from its red giant, a magnitude 10 star barely visible with binoculars.

During the nova event, the white dwarf’s exploding hydrogen envelope will brighten to a magnitude 2 or 3. It will briefly become the brightest star in its home constellation, Corona Borealis. This maximum brightness will last only several hours, and T CrB will fade from visibility with the naked eye in a matter of days.

The view will be very similar across the U.S., but T CrB will get closer and closer to the horizon and will be halfway between where it’s shown here and the horizon by early September. By early October, it will be right on the horizon. Vahé Peroomian/Stellarium

Where to look

Corona Borealis is not a prominent constellation. It’s nestled above Bootes and to the west of Ursa Major, home to the Big Dipper, in northern skies.

To locate the constellation, look due west and find Arcturus, the brightest star in that region of the sky. Then look about halfway between the horizon and zenith – the point directly above you – at 10 p.m. local time in North America.

Corona Borealis is approximately 20 degrees above Arcturus. That’s about the span of one hand, from the tip of the thumb to the tip of the pinky, at arm’s length. At its brightest, T CrB will be brighter than all the stars in Corona Borealis, but not as bright as Arcturus. https://www.youtube.com/embed/4FWiaWlMGLg?wmode=transparent&start=0 To find Corona Borealis, locate Arcturus, and then look about a handspan above.

You can also use an interactive star chart such as Stellarium, or one of the many apps available for smartphones, to locate the constellation. Familiarizing yourself with the stars in this region of the sky before the nova occurs will help identify the new star once T CrB brightens.

Although T CrB is too far from Earth for this event to rival the supernova of 1054, it is nevertheless an opportunity to observe a rare astronomical event with your own eyes. For many of us, this will be a once-in-a-lifetime event.

For children, however, this event could ignite a passion in astronomy. Eighty years in the future, they may look forward to observing it once again.

A Spectacular Sight: The Bright Flash in the Sky Explained

Residents of the Midwest and Southeast were amazed by the flash of a bright “fireball” meteor that lit up the sky last Thursday night, sparking joy and curiosity.

Published

on

Last Thursday night, residents across the Midwest and Southeastern U.S. were treated to an extraordinary celestial event that turned the night sky into a spectacular show. At approximately 9:45 p.m. EST, a brilliant flash lit up the heavens, captivating all who saw it. Reports of the phenomenon poured in, with some onlookers describing the sight as akin to “a basketball on fire.”

Flash


The Flash

But what exactly was this bright object that seized the attention of hundreds? According to Dr. Wes Ryle, an astronomer at the Cincinnati Observatory, this luminous display was caused by a “fireball” – an exceptionally bright meteor hurtling through the Earth’s atmosphere at incredible speeds. These fireballs are large meteoric events that stand out due to their size and the intense light they emit as they burn through the atmosphere.

Frequent Flyers in Our Skies

Interestingly, Dr. Ryle pointed out that such events are more common than most might think. “This kind of thing actually happens pretty frequently,” he remarked during an interview with WXIX Fox 19. He elaborated that even when there isn’t a meteor shower happening, our planet regularly encounters debris from space, from tiny grains of sand to larger objects like the one witnessed on Thursday.

Fireballs: A Rare Encounter

Although meteors regularly enter Earth’s atmosphere, fireballs are considerably rarer due to their larger size. According to Dr. Ryle, “Fireballs appear brighter as they’re going down because they are larger in size.” This makes fireballs a stunning, if not occasional, spectacle in the night sky. If you missed this event, there’s no need to worry; such occurrences happen every few days to a week. However, the visibility of these events greatly depends on whether they occur over populated areas and at times when people are likely to observe them.

Did You Hear That?

More intriguingly, some fireballs can produce sounds if they explode close enough to the Earth’s surface. From the recent event, 15 out of 177 reports included mentions of a sound associated with the fireball, though Dr. Ryle noted it’s hard to confirm whether these sounds were directly related to the fireball.

Where Do They Go?

Most meteors disintegrate and burn up in the atmosphere, but occasionally, some debris might make it to the ground. “If a fireball is sufficiently big, there’s always that chance that some debris will actually land,” Dr. Ryle explained. While finding meteorites—especially in regions like Ohio, Kentucky, or Indiana—can be challenging due to the terrain, modern technology such as Ring doorbell cameras and traffic cameras can help track these meteorites’ trajectories.

A Marvel, Not a Menace

Despite the dramatic flare-up in the sky, Dr. Ryle reassured that such events are not cause for alarm but rather an exciting natural phenomenon to observe. He encouraged people to appreciate these rare sights as part of the incredible world of astronomy.

For anyone eager to learn more or who might have captured this moment on camera, the American Meteor Society welcomes reports, videos, and photos on their website. This interaction helps enhance our understanding of these fiery visitors and their journeys through our sky.

In essence, while the term “shooting star” might be a misnomer, the awe-inspiring sight of a meteor blazing through our atmosphere continues to ignite curiosity and wonder about our celestial surroundings.
