You’ve Got a Rare Chance to See a Huge Asteroid Fly by Earth This Week. Here’s How

In a slow-moving universe, asteroids give us a rare chance to see things moving in real time. We have such a chance coming right up on the evening of Tuesday, January 18th, when 1.1-kilometer asteroid (7482) 1994 PC1 passes 1.23 million miles (1.98 million kilometers) from Earth.   This is about five times the distance … Read more

What will the James Webb Space Telescope look at first?

As the James Webb Space Telescope begins the lengthy process of aligning its 18 primary mirror segments, a question burns in the astronomical community: What will the huge observatory look at first? Webb soared into space successfully on Dec. 25 and successfully completed its major deployments about two weeks later while speeding toward its ultimate … Read more

Astronomers Detect Water Vapor in The Atmosphere of a ‘Super Neptune’ Exoplanet

New Year’s Day comes around once every 47.5 hours on the roughly Neptune-sized exoplanet TOI 674b, which makes it something of a rare creature.  In spite of years of hunting, surprisingly few middle-sized gas giants have ever been seen with orbits shorter than a few days in length, creating what astronomers refer to as a … Read more

Exomoon around Jupiter-like planet possibly spotted by Kepler telescope

A confident detection of a moon orbiting a planet beyond our solar system – called an exomoon – has eluded astronomers so far, but they have found a new candidate Space 13 January 2022 By Leah Crane The exomoon candidate may be orbiting a planet called Kepler-1708b Helena Valenzuela Widerström Astronomers have spotted signs of … Read more

New Breakthrough Lets Scientists Track Mysterious Fast Radio Bursts in Real-Time

Located in the Okanagan Valley outside of Penticton, British Columbia, there is a massive radio observatory dedicated to observing cosmic radio phenomena. It’s called the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a cylindrical parabolic radio telescope that looks like what snowboarders would call a “half-pipe”. This array is part of the Dominion Radio Astrophysical Observatory … Read more

James Webb Space Telescope begins lining up its golden mirrors

Just weeks after the excitement of launch, the James Webb Space Telescope is already seeking focus in space. Engineers are beginning alignment procedures for the recently unfolded 18-segment massive golden mirror. The work will eventually get these individual reflectors working as a single focusing device, NASA officials wrote in a blog update posted on Wednesday … Read more

NASA’s newly launched X-ray space telescope is ready to start observing the cosmos

CAPE CANAVERAL, Fla. — NASA’s newest space observatory, the Imaging X-ray Polarimetry Explorer (IXPE), is set to begin spying on some of the universe’s most dramatic objects — black holes and neutron stars — potentially changing our understanding of the cosmos in the process.  The 730-pound (330 kilograms) IXPE satellite launched to orbit on Dec. … Read more

Landmark Webb Observatory Is Now Officially a Telescope

After several tense days of unfurling and clicking its various parts into place, the biggest and most sophisticated space telescope ever launched is now complete. On 8 January, NASA’s James Webb Space Telescope slowly swung the last 3 of its 18 hexagonal mirror segments into position, locking them together into one 6.5-metre-wide, gold-coated cosmic eye. … Read more
