Mars continues to dazzle as the days grow shorter

Astronomy Magazine - Fri, 12/07/2018 - 05:00
Mars continues to put on a nice show these December evenings. The Red Planet appears nearly halfway to the zenith in the southern sky as twilight fades to darkness. The ruddy world shines at magnitude 0.1, as bright as any other early evening object, against the faint backdrop of Aquarius the Water-bearer. As you gaze at Mars with your naked eye, you might assume it’s the only object of interest in the area. But target the planet through binoculars or a telescope and you’ll also see

Astronomers find planets hidden in far-off clouds of gas and dust

Astronomy Magazine - Fri, 12/07/2018 - 05:00
Planet Hunting In a vast cloud of dust and gas 450 light-years from Earth in the Taurus constellation, scientists have found evidence of a treasure trove of super-Earths and Neptune-sized planets. Using the Atacama Large Millimeter Array (ALMA) in Chile, a team of researchers conducted a study of young stars in a gaseous, star-forming region of Taurus. The team observed and imaged 32 stars in the region that are surrounded by protoplanetary disks — rotating disks of dust and gas that surro

Extreme radiation could strip exoplanets of their atmospheres

Astronomy Magazine - Thu, 12/06/2018 - 05:00
If orbiting just 4 million miles from your fiery host star wasn’t bad enough, things might have just gotten even worse. New research shows that stars emitting high levels of ultraviolet (UV) radiation could strip the atmospheres of their ultra-close exoplanets. While observing gas giants that orbit exceptionally close to their host stars, astronomers found that those bombarded with radiation were losing helium from their atmospheres. These results, which were published in multiple studies
