ALMA captures stirred-up planet factory

Science Daily Astronomy - Mon, 2020-08-03 14:00
Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

Early Mars was covered in ice sheets, not flowing rivers, researchers say

Science Daily Astronomy - Mon, 2020-08-03 12:01
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new research. The findings effectively throw cold water on the dominant 'warm and wet ancient Mars' hypothesis, which postulates that rivers, rainfall and oceans once existed on the red planet.

NASA astronauts safely splash down after first commercial crew flight to space station

Science Daily Astronomy - Sun, 2020-08-02 16:47
Two NASA astronauts splashed down safely in the Gulf of Mexico Sunday for the first time in a commercially built and operated American crew spacecraft, returning from the International Space Station to complete a test flight that marks a new era in human spaceflight.

Machine learning finds a surprising early galaxy

Science Daily Astronomy - Sat, 2020-08-01 15:42
New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% solar abundance, breaking the previous record of the lowest oxygen abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently.

NASA sun data helps new model predict big solar flares

Science Daily Astronomy - Fri, 2020-07-31 13:56
Scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.

Stunning space butterfly captured by ESO telescope

Science Daily Astronomy - Thu, 2020-07-30 12:36
Resembling a butterfly with its symmetrical structure, beautiful colours, and intricate patterns, this striking bubble of gas -- known as NGC 2899 -- appears to float and flutter across the sky in a new picture from ESO's Very Large Telescope (VLT). This object has never before been imaged in such striking detail, with even the faint outer edges of the planetary nebula glowing over the background stars.

Breakthrough method for predicting solar storms

Science Daily Astronomy - Wed, 2020-07-29 12:44
Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun's outer atmosphere - something that until now has eluded scientists' direct measurement. Researchers believe this recent discovery could lead to better 'space weather' forecasts in the future.
