At the heart of our own galaxy, there is a dense thicket of stars with a supermassive black hole at the very center. NASA's ...

NASA’s Hubble Space Telescope and the W. M. Keck Observatory in Hawaii have made independent confirmations of an exoplanet orbiting far from its central star. The planet was discovered through a ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Since 1995 scientists have found more than 5,000 exoplanets ...

Astrophysicists have discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing -- an astronomical phenomenon and the only known method capable of ...

Astronomers have, for the first time, found a planet orbiting a binary star system using microlensing. Gravitational lensing is a technique that made its name by aiding in the discovery of galaxies.

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our ...

The abundance of low-mass compact objects, at or below the hydrogen-burning mass limit of 0.08M ⊙ (where M ⊙ is the solar mass), remains an open question. This abundance has implications for such ...

To Hannaleigh Scott, it looked like someone had spilled salt all over a dark tablecloth - just the way any starry night might appear to a casual observer. But this was no ordinary star census. And one ...

Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, ...

In exoplanet hunting today, there seems to be one burning question that nearly every new article published asks: Where did these planets come from? As astronomers discovered the first extrasolar ...
