Webb’s instruments shed new light on the merger between two galaxies and a brilliant burst of star formation.

“This was completely unexpected.”

Stars are essentially large fiery balls of plasma, which is often referred to as the “fourth state of matter” as it forms when gas is heated into a soup of positively charged ions and negatively charged electrons.

The star’s magnetic field is so strong it appears to have “frozen” its surface into a solid outer crust, a press statement reveals.

Now, though, an international group of astronomers has observed a star with a solid outer layer for the first time, casting doubt on widely held preconceptions about the cosmic giants lighting the night sky.

With cost overruns and milestones not met, it is a wonder that NASA and Boeing aren’t headed for a divorce.

Agency budgetary report shows tens of billions spent on Boeing contracts that have yet to deliver. Much cheaper alternatives exist.

It may be known as a rocky, red planet but evidence is mounting that salty water exists at the base of polar deposits on Mars.

University of Southern Queensland’s Professor Graziella Caprarelli is part of an international team investigating bright reflection signals below the Martian surface, first spotted in data acquired between 2010 and 2019 by the radar sounder MARSIS on board Mars Express.

The primarily Italian team proposed that the reflections pointed to a patchwork of salty lakes, publishing their research in Science in 2018 and in Nature Astronomy in 2021. Recently a new collaboration between the Italian team and U.S.-based researchers provided new evidence further corroborating this interpretation.

NASA combined 18 all-sky images to create a timelapse of the night sky.

The Universe is over 13 billion years old, so a 12-year slice of that time might seem uneventful. But a timelapse movie from NASA shows how much can change in just over a decade.
