July 15, 2024

Stargazers and astronomy enthusiasts, mark your calendars! After a 68-year voyage through the vast reaches of our solar system, Comet 13P/Olbers is making a grand return, bringing with it a spectacular opportunity for celestial observations. On July 20, 2024, this fascinating cosmic traveler will be at its closest point to Earth, offering a unique glimpse into the dynamic and ever-changing universe we live in.

A Brief History of Comet 13P/Olbers

Discovered on March 6, 1815, by the German astronomer Heinrich Olbers, the comet that now bears his name has intrigued astronomers for over two centuries. Olbers, observing from Bremen, noticed the comet when it was faintly visible to the naked eye. Since its discovery, this periodic comet – named so due to its regular returns to the inner solar system – completes an orbit around the sun every 68 years.

The Spectacular 2024 Close Approach

This year, Comet 13P/Olbers made its perihelion (closest approach to the sun) on June 30 and is now racing towards its closest approach to Earth. On the evening of July 20, it will be about 176 million miles (283.5 million km) from our planet. Despite this considerable distance, Comet 13P/Olbers is currently the brightest comet gracing our skies, primarily found in the constellation of Ursa Major but swiftly moving toward Leo Minor in the northwestern sky.

How to Observe Comet 13P/Olbers

For those eager to catch a glimpse of this celestial wanderer, the current week offers the prime viewing window. Although the comet’s brightness is pegged at a magnitude of 6.5 to 7 – typically below the threshold of visibility to the naked eye – it should be readily observable through binoculars or a small telescope.

Observers in the Northern Hemisphere are particularly in luck, as they’ll have the best chance of spotting the comet. If you’re near the equator, try your luck by searching low on the horizon just after sunset, especially around July 16 when Comet 13P/Olbers will pass close to the irregular galaxy NGC 3104 in Leo Minor. This close passage not only provides a treat for the eyes but also a golden opportunity for astrophotographers looking to capture both the comet and galaxy in one frame.

A Celestial Event Not to Miss

Considering the next return of Comet 13P/Olbers is slated for March 2094, this year’s close approach serves as a rare and significant event for both amateur and professional astronomers. The comet’s journey through the cosmos is a reminder of the relentless and beautiful dynamism of our universe.

So whether you’re a seasoned astronomer with sophisticated equipment or an amateur stargazer with a simple pair of binoculars, make sure to step outside and take advantage of this cosmic spectacle. Observing and appreciating heavenly events like the return of Comet 13P/Olbers not only enrich our understanding of the universe but also add to the collective wonder and mystery of our starry skies.

Don’t miss the chance to observe Comet 13P/Olbers as it makes its closest approach to Earth on July 20, 2024. It’s a fleeting visit, and one not to be repeated for another 70 years. Grab your telescopes and binoculars, and look up to the stars, for there lies a wanderer from the depths of space, momentarily close enough to whisper the secrets of the cosmos.

Near-Earth Object 2024 UQ: A Close Call from the Cosmos

Published

4 days ago

November 10, 2024

Rod Washington

In a remarkable demonstration of both the unpredictability of space and the extraordinary capabilities of modern astronomical detection, a small asteroid, designated 2024 UQ, recently made headlines after it struck Earth just hours after being identified. This event, which took place on October 22, 2024, marks the third “imminent impactor” recorded this year, highlighting the continual and often daunting reality of near-Earth objects (NEOs).

Discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii, a network of four telescopes dedicated to scanning the night sky for potential collision threats, 2024 UQ was small—measuring only about 3 feet (1 meter) in diameter. While news of an asteroid making contact with Earth can evoke concern, there was no cause for alarm in this instance. The diminutive size of the asteroid meant that it posed very little threat to anything on the ground. In fact, it burned up in the atmosphere over the Pacific Ocean near California, leaving no trace or damage.

However, the swift timeline of events raises critical questions about the effectiveness of our current monitoring systems. The impact occurred just two hours after the initial detection, which meant that by the time data was transmitted to the impact monitoring systems operated by the European Space Agency’s Near-Earth Object Coordination Center, the impact had already taken place. According to their November 2024 newsletter, the ATLAS survey had successfully obtained images identifying the asteroid on a collision trajectory, but due to its position near the edge of two adjacent observational fields, it was not recognized as a significant threat until it was too late.

This incident serves as a reminder of the complexities involved in tracking and predicting the paths of NEOs. While advancements in technology have undoubtedly improved our ability to detect these celestial objects, the circumstances surrounding 2024 UQ showcase the potential for oversights in our monitoring capabilities. Despite this event being minor in scale, it emphasizes the importance of continued investment in space surveillance systems, as well as international collaboration in tracking potential hazards lurking in the vast expanse of space.

Charles Elliot

In a striking reminder of the cosmos’s potential threats, NASA has issued a warning about a stadium-sized asteroid hurtling towards Earth at an astonishing speed of 16 kilometers per second. Designated as 2024 RV50, this massive rock measures approximately 710 feet in width and is set to pass our planet on October 18, 2024.

What We Know About 2024 RV50

Discovered relatively recently on September 1, 2024 RV50 belongs to the Apollo group of asteroids, which are known for their orbits that bring them close to Earth. The asteroid takes about 769 Earth days—roughly 2.1 years—to complete its orbit around the Sun, traveling at distances that can reach up to 386 million kilometers from the Sun and coming as close as 105 million kilometers.

NASA’s Jet Propulsion Laboratory (JPL) is diligently monitoring the asteroid’s trajectory using advanced tracking systems. According to current calculations, 2024 RV50 will pass Earth at a distance of approximately 7.42 million kilometers, which may seem far, but in astronomical terms, it’s a close encounter.

Potentially Hazardous?

While 2024 RV50 is classified as a potentially hazardous object due to its size and proximity to Earth, NASA assures us that it does not pose a threat. The risk of any significant impact is minimal, and the asteroid’s current trajectory suggests it will safely pass by our planet. For context, the next encounter with Earth is projected for October 18, 2064, when it will come even closer at a distance of about 5.67 million kilometers.

The Importance of Monitoring Asteroids

NASA’s ongoing efforts to track and monitor asteroids are crucial. These ancient celestial bodies provide insights into the early solar system, as they are remnants of the material that formed planets. Understanding their trajectories and potential impacts is essential for planetary defense, especially since history has shown that asteroid impacts have drastically altered Earth’s biosphere. The infamous asteroid that struck the Yucatán Peninsula 6.5 million years ago is believed to have contributed to the extinction of 75% of Earth’s species, including the dinosaurs.

Through advanced observation techniques and modeling, NASA aims to predict potential threats and develop mitigation strategies. Continuous monitoring of such objects not only helps safeguard our planet but also enriches our understanding of the solar system’s history.

As we prepare for the passing of 2024 RV50, it serves as a reminder of the dynamic nature of our universe and the importance of vigilance in the face of potential cosmic threats. NASA’s commitment to tracking these celestial bodies ensures that we remain informed and prepared for whatever the universe may send our way.

Greetings, stargazers! If you missed the breathtaking display of the Northern Lights this past Thursday or are simply craving another celestial spectacle, there’s an unmissable show taking place in the night sky right now—Comet Tsuchinshan-ATLAS. Also known as C/2023 A3, this comet has recently made its closest approach to Earth, and it’s treating us with a glorious exhibition as it makes its way across the post-sunset western horizon.

When and Where to Look

Tonight, Sunday, October 13th, is the perfect opportunity for observers in the northern hemisphere to catch a glimpse of Comet Tsuchinshan-ATLAS. Approximately 45 minutes after sunset, keep your eyes peeled toward the western horizon. Although it’s close to reaching its intrinsic brightest, spotting the comet just after sunset could be challenging due to fading twilight. However, don’t let the bright, 83%-lit waxing gibbous moon discourage you, as its brightness won’t interfere with your viewing.

How to Spot the Comet

Using some well-known celestial reference points can help you locate the comet. First, ensure you have a clear view of the western horizon. Find the bright planet Venus and the bright star Arcturus—they will be close to the horizon. Comet Tsuchinshan-ATLAS will be situated slightly below a midpoint between these two brilliant points.

Although you might be able to spot the comet with your naked eyes, a pair of binoculars will enhance your view. The comet will rise a little higher in the sky this weekend compared to previous nights, providing a clearer view. Still, the observing window will be relatively short as the comet will quickly sink below the horizon again.

Upcoming Opportunities

If you’re unable to view the comet tonight, don’t worry. According to Sky & Telescope, the comet-watching conditions will improve as we move into the next week. Monday, October 14th, and Tuesday, October 15th are projected to offer the best viewing experiences since the comet will appear against a darker sky. Be sure to check back for our detailed viewing guides for those nights.

It’s important to note that comets—and weather conditions—can be unpredictable, so take advantage of clear skies whenever possible.

A Glimpse into History

Comet Tsuchinshan-ATLAS is more than just a fleeting celestial visitor; it’s an extraordinary long-period comet that hails from the Oort Cloud, the distant sphere of icy bodies that encircles our solar system. This comet makes an incredibly rare journey into the inner solar system only once every 80,000 years—a historic event to witness!

Discovered in early 2023 by astronomers from China’s Tsuchinshan Observatory, with its presence confirmed by the ATLAS telescope in South Africa, Comet C/2023 A3 represents both scientific curiosity and natural beauty.
