The James Webb Telescope spots its first supernova

The James Webb Telescope spots its first supernova

“Primarily, it’s exciting because we have shown that we’re able to find and detect new transients with Webb, which was something that JWST is not designed to do,” continued Engesser. “But it’s one of the things we’re showing we’re able to do in sort of an ad hoc way.” JWST Finding celestial objects like supernovas … Read more

Four astronomers respond to the first images from the James Webb Space Telescope

Four astronomers respond to the first images from the James Webb Space Telescope

It’s finally happening. After decades of planning and years of setbacks. After a harrowing launch and deployment during which 344 different problems could have sunk the $10 billion instrument. After six long months of commissioning and coming online, the most powerful telescope ever built is finally returning images. And they’re spectacular. At Interesting Engineering, we’ve … Read more

Astronomers Have Detected a Rotating Galaxy From The Early Days of The Universe

Astronomers Have Detected a Rotating Galaxy From The Early Days of The Universe

A team of astronomers have used the ALMA telescope to find a slowly-rotating galaxy in the early Universe. That galaxy is the youngest ever found with a measured rotation, and it’s much slower than present-day galaxies. All galaxies rotate, usually at incredible speeds. For example, the Milky Way galaxy has a rotation speed of over … Read more

Astronomers Watched a Black Hole Shred a Star – But Surprisingly Little Was Devoured

Astronomers Watched a Black Hole Shred a Star – But Surprisingly Little Was Devoured

What happens when a star wanders too close to a supermassive black hole? The obvious story is that it gets sucked in, never to be seen again. Some of its material gets superheated on the way in and that gives off huge amounts of radiation – usually X-rays. That’s not a wrong explanation, just incomplete. … Read more

Astronomers explain why Uranus is lighter in color than Neptune

Astronomers explain why Uranus is lighter in color than Neptune

Neptune and Uranus are similar in size and atmospheric conditions but curiously, Neptune is a darker shade of blue. Astronomers used observations from the international Gemini Observatory, a program of NSF’s NOIRLabthe NASA Infrared Telescope Facility and Hubble Space Telescope to develop an atmospheric model that explains the difference in hue between the here planets. … Read more

Researchers discover new ‘stellar systems’ of blue stars

Researchers discover new ‘stellar systems’ of blue stars

A new class of stellar systems has been identified, they’re not quite galaxies and only exist in isolation, according to the researchers at University of Arizona. The new stellar systems contain only young, blue stars, which are distributed in an irregular pattern and seem to exist in surprising isolation from any potential parent galaxy. Also … Read more

Astronomers find fastest-growing black hole of past 9 bn years

Astronomers find fastest-growing black hole of past 9 bn years

An international team of astronomers has discovered the fastest-growing black hole of the last nine billion years. The black holes consumes the equivalent of one Earth every second and shines 7,000 times brighter than all the light from our own galaxy, making it visible to well-equipped backyard astronomers, said the team from the Australian National … Read more

An Ultra-Rare Cosmic Object Was Just Detected in The Milky Way, Astronomers Report

An Ultra-Rare Cosmic Object Was Just Detected in The Milky Way, Astronomers Report

A new member of a category of star so rare we can count the known number of them on our fingers and toes has just been discovered in the Milky Way. It’s called MAXI J1816-195, located no greater than 30,000 light-years away. Preliminary observations and investigations suggest that it’s an accreting X-ray millisecond pulsar – … Read more

Census of 140,000 Galaxies Reveals a Surprising Fact About Their Stars

Census of 140,000 Galaxies Reveals a Surprising Fact About Their Stars

How many of what kinds of stars live in other galaxies? It seems like a simple question, but it’s notoriously hard to pin down because astronomers have such a difficult time estimating stellar populations in remote galaxies. Now a team of astronomers has completed a census of over 140,000 galaxies and found that distant galaxies … Read more
