Astronomers have identified the first two twin stars doomed to collide in a kilonova explosion

Although massive stars usually die in spectacular explosions, only a handful of them fizzle out like failed fireworks. Astronomers have located the remnants of one of these unexploded fireworks in SGR 0755-2933, a neutron star About 11,400 light-years away a land In the southern constellation Puppis. In new research, scientists say that earlier in his …

Astronomers say that asteroids made of "rubble" may be very difficult to destroy

Astronomers say that asteroids made of “rubble” may be very difficult to destroy

Although a common premise in science fiction, the possibility of a large asteroid crashing into Earth is not a fantasy at all, but a guarantee. An asteroid extinction event is a periodic event, just like a tidal wave or a full moon. Just ask the dinosaurs. That’s why the National Aeronautics and Space Administration (NASA) …

Astronomers have just caught a 9-billion-year-old radio signal from space

in resident alienIn the season 2 episode “Radio Harry” (now airing on Peacock!), Harry takes his alien communications device to the top of a mountain in order to get the best contact with the extraterrestrial transient radio transmitter humans know as ‘Oumuamua. You may remember ‘Oumuamua as the first discovered extraterrestrial object that made headlines …

A doomed world: Astronomers discover an exoplanet spiraling toward its destruction

Ashley Chontos, Henry Norris Russell’s Princeton postdoctoral fellow in astrophysics, was part of a team that discovered Kepler-1658b is nearing perdition around its aging star, providing an opportunity to learn more about the fate of other worlds as their solar systems evolve. Chontos also led the 2019 effort to confirm that this object was an …

Astronomers have just realized that the Milky Way is very large in relation to its surroundings

Astronomers have just realized that the Milky Way is very large in relation to its surroundings

Our home, the Milky Way, doesn’t look particularly strange for a galaxy. Medium in size, spiral in shape, with some kinks suggestive of a turbulent past. But astronomers have just identified an oddity unprecedented in any galaxy studied to date: the Milky Way is very large relative to its surroundings. Specifically, it appears to be …

Google Space Maps: Astronomers create an unprecedented, detailed map of the Milky Way

Google Space Maps: Astronomers create an unprecedented, detailed map of the Milky Way

In science fiction series like “Star Trek” and “Star Wars,” spaceships can fly around the galaxy thanks to detailed star maps that you navigate in faster-than-light ships. Here on Earth, we lack a Google Maps replica of the Milky Way — or at least we did. That’s because astronomers have recently released a new, more …

Astronomers weighed our Milky Way, which is lighter than expected

For more than a decade now, so-called fast radio bursts (FRBs) have mystified scientists. These very short, bright flashes of radio waves happen across the sky all day, but no one yet knows what causes them. Although FRBs are still a mystery, new observations of this strange phenomenon may actually help astronomers learn more about …

The James Webb Space Telescope launched on Dec. 25, 2021.

After the James Webb Space Telescope, what’s the next big thing for astronomers?

What would it take to build more than 20,000 engineers and hundreds of scientists? Space Telescope – Specifically, the James Webb Space Telescope. Fortunately, the effort has been worthwhile, with a slew of amazing results from NASA’s newest observatory in the first six months of science operations. But what then? John Mather, Nobel Prize-winning astronomer …

A photo of comet C/2022 E3 ZTF taken on Dec. 26, 2022 in Payson, Arizona by Chris Schur.

Astronomers say the bright green comet is a ‘rare messenger from the outer reaches of our solar system’

A comet not seen from Earth in tens of thousands of years can be seen in the sky this month. Comet C/2022 E3 (ZTF) was discovered on March 2, 2022 by astronomers Frank Massey and Bryce Paulin using the Zwicky Transit Facility (ZTF) at Palomar Observatory in California. At the time, the comet was located …

Astronomers plot the magnetic field of a giant bubble surrounding Earth

Astronomers plot the magnetic field of a giant bubble surrounding Earth

Our planet is surrounded by a huge “giant bubble” 1,000 light-years across. Now, astronomers have made the first 3D map of its magnetic field. The giant structure, known as the Local Bubble, is a hollow bubble of hot, diffuse plasma surrounded by a shell of cold gas and dust from which surface stars are forming. …
