Yale astronomer Priyamvada Natarajan helped do something extraordinary — reach back to the dawn of time to discover the glimmers of an ancient quasar. Using a pair of space borne telescopes, Natarajan and her research team found UHZ1, just 450 million years after the Big Bang and far outside our own galaxy. Moving farther away…

Astronauts dropped a tool bag during an ISS spacewalk, and you can see it with binoculars
Some astronomy targets are less celestial in nature than others. Joining stars, planets, nebulas, and galaxies as a target for skywatchers is now a surprisingly bright tool bag floating through the space around Earth. The bag of tools gave NASA astronauts Jasmin Moghbeli and Loral O’Hara the slip on Nov. 2, 2023, as they were…

What did ancient humans know about astronomy?
Imagine going back thousands of years and showing off the cool astronomical functions of your smartphone. It can tell the date and time with incredible accuracy. It can pinpoint your location. It can even pull up a map of the stars, tell you the phases of the moon, and predict the next major astronomical event.…

I review star projectors for a living and this early Black Friday deal is one of the best I’ve seen all year.
No astronomy enthusiast’s home is complete without one of the best star projectors to light up those dark, cold evenings (that have well and truly arrived!) We have reviewed many models of star projectors and selected the best to feature in our Best Star Projector guide. The Pococo model is one of our favorites, and…

Tis the season! Behold the Christmas Tree Galaxy Cluster
Yes, it’s technically only November. But that doesn’t mean astronomers can’t start getting in the spirit of the holiday season! They’re putting up the Christmas Tree early, thanks to a joint-present from NASA’s James Webb and Hubble Space Telescopes. The striking image, dubbed the Christmas Tree Galaxy Cluster, combines visible light from Hubble and infrared…

X-37B Aiming For New Orbit With Launch On Falcon Heavy
The U.S. Space Force plans to launch its next X-37B mission aboard a SpaceX Falcon Heavy, aiming for a new orbit. The mission, known as USSF-52, will be the seventh for the two-vehicle fleet of Boeing-built X-37B Orbital Test Vehicles (OTV). Liftoff from the Kennedy Space Center is targeted for Dec. 7. The 29-ft. reusable…

These small galaxies were shredded by their larger siblings
While galaxies appear to be lonely wanderers in the vast universe, many in fact huddle closely in clusters, held together by their collective gravity. And sometimes, it would appear, they also munch on one another. In other words, larger galaxies in these pockets merge with and gobble smaller ones to grow even bigger — our…

9 things we still don’t know about the Universe
While it would seem that scientists and astronomers know an awful lot about the Universe, we are nowhere near knowing everything there is to know. Yet every one in a while, astronomers make a breakthrough in our understanding of the Universe, and our perception of how the Universe works is substantially shifted. Take for example…

NASA’s Webb, Hubble telescopes combine to create most colorful view of universe
image: Panchromatic view of MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. The image was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting prismatic panorama of blues and reds give clues to the distances of the galaxies. view more Credit:…
