Using the ARO 12-m telescope, astronomers have investigated a young starless core known as Lynds 1521E (or L1521E). The study resulted in the detection of complex organic molecules in this object. The finding is detailed in a paper April 15 on the arXiv pre-print repository.

Starless cores are dense, cold regions within interstellar molecular clouds. They represent the earliest observable stage of low-mass star formation. Observations show that even in such cold environments, complex organic molecules can be present...

A new study led by a planetary scientist uses a computer model of Mars to put forth a promising explanation onto how Mars once contained rivers and lakes: Mars could have had a thin layer of icy, high-altitude clouds that caused a greenhouse effect.

One of the great mysteries of modern space science is neatly summed up by the view from NASA’s Perseverance, which just landed on Mars: Today it’s a desert planet, and yet the rover is sitting right next to an ancient river delta.

The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third as much sunshine as we ...

Stars spin faster than expected as they age according to a new study led by scientists at the University of Birmingham which uses asteroseismology to shed new light on this emerging theory.

All stars, like the Sun, are born spinning. As they grow older, their spin slows down due to magnetic winds in a process called ‘magnetic braking’. Research published in 2016 by scientists at Carnegie Observatories delivered the first hints that stars at a similar stage of life as the Sun were spinning faster than magnetic braking theories predicted. The results from this study were based on a method in which scientists pinpoint dark spots on the surface of stars and track them as they move with the stars’ spin...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age...
