Astronomers discover evidence for most powerful pulsar in distant Milky Way

As the supernova’s explosive debris shell expands over a few decades, it becomes less dense and eventually thin enough to allow radio waves to escape from within. This allowed observations by the VLA Sky Survey to detect bright radio emission created as the fast-spinning neutron star’s powerful magnetic field sweeps through surrounding space, accelerating charged … Read more

Astronomers reveal the most detailed map of the metallic asteroid Psyche ever

If you wanted to do a forensic study of the solar system, you could go to the main asteroid belt between Mars and Jupiter. That’s where you can find ancient rocks from the early days of the solar system. Out there in the cold vacuum of space, far from the sun, asteroids are largely untouched … Read more

Mysterious blue blobs could be galactic ‘belly flops’, astronomers say

Astronomers from UArizona have identified a new class of galaxies. The collection of mostly young blue stars can be seen here using the Hubble Space Telescope Advanced Camera for Surveys. Credit: Michael Jones Astronomers at the University of Arizona have found five examples of a new class of galaxies. They are not actually galaxies and … Read more

Astronomers discover a nearby multiplanet system with two Earth-sized planets

New Multiplanet System Near Earth

MIT astronomers have discovered a new multiplanet system located just 10 parsecs, or about 33 light-years, from Earth, making it one of our most well-known multiplanet systems. The star at the heart of the system is likely to host at least two Earth-sized terrestrial planets. Credit: MIT News, with TESS Satellite figure courtesy of NASA … Read more

Astronomers may have discovered a ‘dark’ free-floating black hole

image: Hubble Space Telescope image of a distant star that was brightened and distorted by an invisible but very compact and massive object between the star and Earth. The compact object — estimated by UC Berkeley astronomers to be 1.6 to 4.4 times the mass of our sun — could be a free-floating black hole, … Read more

Stellar “ghost” discovered: Astronomers may have detected a “dark” free-floating black hole

When massive stars come to the end of their lives and explode in a supernova, they leave behind a black hole. It is estimated that about one in a thousand stars is massive enough to give … Read more
