Astronomers spot the largest potentially dangerous asteroid detected in the last eight years
Twilight observations with the Dark Energy Camera made by the US Department of Energy at NOIRLab’s Cerro Tololo Inter-American Observatory in Chile have allowed astronomers to spot three near-Earth asteroids (NEAs) hidden…
Astronomers discover a doomed Earth-sized world around a violent star
And if you placed an Earth-sized planet in a close orbit around an M dwarf star? This is more than an academic question, since M dwarfs are the most numerous stars we…
Images of NASA’s Webb Pillars of Creation offer astronomers more than just pretty pictures
This combined image provided by NASA on Wednesday, October 19, 2022 shows the Pillars of Creation … [+] as shown by NASA’s Hubble Space Telescope in 2014, left, and NASA’s James Webb…
Astronomers discover a planetary system with a Neptune-mass planet and a massive substellar object

Why the stunning ‘Pillars of Creation’ photo from the James Webb Space Telescope has astronomers buzzing
The James Webb Space Telescope has taken a breathtaking look inside the “Pillars of Creation”, a spectacular formation of dust clouds made famous by its predecessor, the Hubble Space Telescope. The image…
A desolate world had completely blown the atmosphere away, astronomers think
What if you put an Earth-sized planet in a close orbit around an M dwarf star? This is more than an academic question, since M dwarfs are the most numerous stars we…
Supernova alert! Now astronomers have a warning system when stars explode!
In Oversight, humanity tries to recover from a narrowly won war against an alien species. We survived, but the planet is destroyed and the only hope – at least according to the…
Astronomers discover a ‘marshmallow world’: the lowest-density gas giant ever discovered
The exoplanet discovery space hosts all kinds of interesting “super” worlds. There are super-Earths, super-Neptunes and, of course, super-Jupiters. Recently, the WIYN telescope on Kitt Peak in Arizona made a follow-up observation…
Astronomers map the influence of dark matter and dark energy on the universe by measuring more than 1,500 supernovae
In 2011, the Nobel Prize in Physics was awarded to Perlmutter, Schmidt and Reiss for their discovery that the universe is not just expanding, it is accelerating. The work supported the idea…
