Infant “Hot Neptune” Provides Clues to Its Birth

How’d a nice young ice giant end up in such a hot orbit? Scientists investigate the mysterious exoplanet AU Microscopii b.

Red Dwarfs Aren’t So Bad (For Planets) After All

Red dwarf stars appear to flare preferentially at high latitudes, which might keep their exoplanets habitable instead of hellish.

A Pileup of Perpendicular Planets

In some planetary systems, the direction that a star spins and the direction its planets orbit don’t always line up. A new study explores what we can learn from these nonconformists.

Astronomers Detect Potential Moon-forming Disk around an Exoplanet

Astronomers have made the first clear detection of a dusty disk surrounding an exoplanet, which could eventually go on to form moons.

Gravitationally Unstable Disk May Collapse to Form Planets

Astronomers investigate the spiral arms of a young star's disk and find evidence of a disk so massive that it could collapse to form planets.

NASA’s Kepler Finds Outcast Earths

Astronomers uncovered four new Earth-mass rogue planet candidates by searching for microlensing events observed with Kepler.

Astronomers Challenge Claim of Planet Around Barnard's Star

Astronomers thought a super-Earth might orbit nearby Barnard's star. But a new study disputes that claim, arguing that stellar activity might be masquerading as the planetary signal.

Proxima Centauri Releases Powerful Flare

The Sun dwarfs its nearest stellar neighbor, but Proxima Centauri's flares pack a comparatively energetic punch.

Far-out Gas Giant Exoplanet Puzzles Astronomers

Astronomers have discovered a super-Jupiter orbiting its young star on a surprisingly wide orbit. How did it get there?

Spotting a Faint Escaping Atmosphere

Low-density exoplanets orbiting close to their host stars tend to lose their atmosphere. Now, astronomers can measure how fast it disappears.

Rocky Planet Found Around 10 Billion-Year-Old Star

Astronomers have found an Earth-size (but not at all Earth-like) planet around an ancient star that has a nice high view of our galaxy.

Radio Transmission from a Brown Dwarf

The radio discovery of a brown dwarf holds promise for future exoplanet detections.

Earth-size Planets Are Common, Kepler Retrospective Finds

A new, full analysis of Kepler data finds at least 300 million Earth-size planets in the habitable zone around Sun-like stars in our galaxy.

60-second Astro News: Mature Infant Galaxies & A Possibly Rogue Planet

This week in astronomy news: Distant galaxies that look older than they are and a terrestrial planet that might be drifting through our galaxy.

Giant Planet Found Around a White Dwarf

Astronomers have found a Jupiter-size planet orbiting a much smaller white dwarf. The discovery shows what a system might look like after its star's death.

First Image of a Young Sun and Two Giant Planets

For the first time, astronomers have imaged multiple planets orbiting a Sun-like star.

Alignment of a Star and a Planet

Unlike in our solar system, not all planets orbit in the same direction as their stars rotate. A nearby planetary system may reveal how these orbits form.

Close Encounters in the Milky Way — and What They Mean for Planets

New research shows stellar flybys are common in our galaxy’s crowded center. That could have both good and bad (but mostly bad) effects on growing planets.
