Giant exoplanet hunters: Look for debris disks

There's no map showing all the billions of exoplanets hiding in our galaxy—they're so distant and faint compared to their stars, it's hard to find them. Now, astronomers hunting for new worlds have established a possible ...

Hunting molecules with the Murchison Widefield Array

Astronomers have used an Australian radio telescope to observe molecular signatures from stars, gas and dust in our galaxy, which could lead to the detection of complex molecules that are precursors to life.

CHESS mission will check out the space between stars

Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium—that may, over millions of years, ...

VST captures three-in-one

Two of the sky's more famous residents share the stage with a lesser-known neighbour in this enormous new three gigapixel image from ESO's VLT Survey Telescope (VST). On the right lies Sharpless 2-54, the iconic Eagle Nebula ...

Understanding star-forming galaxies

The more stars a typical spiral galaxy contains, the faster it makes new ones. Astronomers call this relatively tight correlation the "galaxy main sequence." The main sequence might be due simply to the fact that galaxies ...

Next breakthroughs in exoplanet discovery

It was a good week for astrobiology. Within days of NASA's announcement that the necessary ingredients for life exist in the plumes erupting from the southern pole of Saturn's moon Enceladus, scientists gathered at Stanford ...

Star in closest orbit ever seen around black hole

Astronomers have found evidence of a star that whips around a likely black hole twice an hour. This could be the tightest orbital dance ever seen by a black hole and a companion star in our own Milky Way galaxy.
