How to Watch a Stadium-Size ‘Potentially Hazardous’ Asteroid Zip by Earth Today

Aspace rock measuring a fifth of a mile across (about a third of a kilometer) is set to fly by Earth on Monday, and one online observatory is offering a close-up look.  The asteroid named 1999 VF22 will officially be nearest to our planet at 11:54 p.m. PT, when it zips past at a distance over 3.3 million miles (5.4 million kilometers), its closest pass … Continue reading How to Watch a Stadium-Size ‘Potentially Hazardous’ Asteroid Zip by Earth Today

Mega Comet Arriving From the Oort Cloud Is 85 Miles Wide

Bernardinelli-Bernstein is officially the largest comet ever discovered, according to updated observations of the inbound object. Oort Cloud comet C/2014 UN271, also known as Comet Bernardinelli-Bernstein, measures some 85 miles (137 km) in diameter, give or take 10.5 miles (17 km), reports a research team led by astronomer Emmanuel Lellouch of the Paris Observatory. Their new paper on the mega comet has been accepted for … Continue reading Mega Comet Arriving From the Oort Cloud Is 85 Miles Wide

Moon phases 2022: This year’s moon cycles

Moon phases reveal the passage of time in the night sky. Some nights when we look up at the moon, it is full and bright; sometimes it is just a sliver of silvery light. These changes in appearance are the phases of the moon. As the moon orbits Earth, it cycles through eight distinct phases. The four primary phases of the moon occur about a … Continue reading Moon phases 2022: This year’s moon cycles

Astronomers witness the explosive death of a giant star for first time

For the first time, astronomers have observed the final days and death throes of a red supergiant star before its final collapse and massive explosion into a supernova. Supernovas are usually only detected after they happen, although a few of a different type have been caught in the act of exploding. In this case, scientists detected the star in its final stages about 130 days … Continue reading Astronomers witness the explosive death of a giant star for first time

Massive comet as large as small planet barreling toward our solar system

A massive comet — so large that scientists had previously mistaken it for a dwarf planet — is hurtling through space toward our solar system and is expected to arrive in about 10 years, new research revealed. The Bernardinelli-Bernstein comet is an estimated to be 60-120 miles across, 1,000 times larger than a traditional comet, astronomers said when its discovery was first announced in June. It … Continue reading Massive comet as large as small planet barreling toward our solar system
