For a few tense days this January, a roughly 70-meter asteroid became the riskiest observed in over a decade. Despite the Moon’s attempt to scupper observations, the asteroid is now known to be entirely safe.
Initial observations of an asteroid dubbed ‘2022 AE1’ showed a potential Earth impact on July 4, 2023 – not enough time to attempt deflection and large enough to do real damage to a local area should it strike.
Ingenious System to Pulverize Asteroids May Be Earth's Only Chance in a Catastrophe
Gazing at the night sky can evoke a sense of wonder regarding humanity's place in the Universe. But that's not all it can evoke.
If you're knowledgeable about asteroid strikes like the one that wiped out the dinosaurs , then even a fleeting meteorite can nudge aside your enjoyable sense of wonder.
NASA's plans to prevent a potential asteroid impact catastrophe explained
To find the answers to these questions, one has to know what near-Earth objects are out there. To date, NASA has tracked only an estimated 40% of the bigger ones . Surprise asteroids have visited Earth in the past and will undoubtedly do so in the future.
Millions of objects of various sizes orbit the Sun. Near-Earth objects include asteroids and comets whose orbits will bring them within 120 million miles (193 million kilometers) of the Sun.
Amateur Astronomers Team Up to Measure Distance to a Close-passing Asteroid - Sky & Telescope ...
On the afternoon of December 19, 2021, our team of amateur astronomers in two towns in Italy, Cremona and Salerno, observed the close passage of the near-Earth asteroid 163899 (2003 SD220). Our observations enabled us to calculate its distance using the parallax method.
The parallax of an object is its apparent shift based on the angle from which we've viewing it, in the same way that a finger held close to your eyes appears to move depending on whether you're watching it with your left or right eye.
Last-Minute Defense Against an Asteroid That Could Obliterate it Before Impact - Universe Today
Gazing at the night sky can evoke a sense of wonder regarding humanity’s place in the Universe. But that’s not all it can evoke.
Luckily, planetary defence is at the top of mind for some scientists and engineers. One of those scientists is Professor Philip Lubin from the University of California Santa Barbara. Lubin is developing his idea called PI-Terminal Defense for Humanity.

A new way of dating collisions between asteroids and planetary bodies throughout our Solar System’s history could help scientists reconstruct how and when planets were born.
Satellite Spots Massive Asteroid Impact Crater in China
In 2019, researchers first described a 1.15-mile-wide crater in a mountain range in northeast China; late la st year, a NASA satellite imaged the crater from space, giving a broad new view the impact's aftermath.
The southern rim of the crater has eroded , so from above the impact site looks more like a crescent. The rim is nearly 500 feet tall at its highest points, the researchers reported, and is slightly wider than China's previously confirmed impact strucgture , Xiuyan, which is 1.12 miles across.
Tonga volcano eruption yields insights into asteroid impacts on Earth | Space
On Jan. 15, 2022, the Hunga Tonga-Hunga Ha'apai volcano erupted off the coast of Tonga in the South Pacific Ocean, generating a tsunami and triggering resulting wave action alerts around the world.
The underwater volcanic eruption spewed ash, steam, and gas a radius of over 160 miles (260 kilometers) and more than 12 miles (19 km) into Earth's atmosphere .
Space Force: Season 2's Shocking Ending, Explained | CBR
WARNING: The following contains major spoilers for Season 2 of Space Force , now available on Netflix.
Netflix's Space Force pushed General Naird to the limit in Season 2 as he tried to ensure the American space initiative could stay afloat. After a fracas involving China's astronauts on the moon, the titular group had its budget slashed, creating tension and anger at the office.
