Sunspots could soon disappear for decades: study

(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades. ...

Turning Planetary Theory Upside Down (w/ Video)

(PhysOrg.com) -- The discovery of nine new transiting exoplanets is announced today at the RAS National Astronomy Meeting. When these new results were combined with earlier observations of transiting exoplanets astronomers ...

50 new exoplanets discovered by HARPS

Astronomers using ESO's world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By ...

Rare extreme helium star identified by astronomers

(Phys.org)—Astronomers have identified another rare example of an extreme helium star. The star, designated GALEX J184559.8−413827 (or J1845−4138 for short), was initially classified as a faint helium-rich "hot subdwarf," ...

True colour of exoplanet measured for the first time

(Phys.org) —Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true colour of a planet orbiting another star. If seen up close this planet, known as HD 189733b, would be a deep ...

Giant black holes revealed in the nuclei of merging galaxies

Subaru Telescope research team led by Dr. Masatoshi Imanishi at the National Astronomical Observatory of Japan sampled many infrared bright, merging galaxies and determined the presence of active supermassive black holes ...

A 3-D view of remote galaxies

For decades, distant galaxies that emitted their light six billion years ago were no more than small specks of light on the sky. With the launch of the Hubble Space Telescope in the early 1990s, astronomers were able to scrutinise ...
