Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence.

In a new study, researchers report on the most detailed simulation ever of a large patch of the intergalactic medium (IGM). For the first time, they were able to see how cold, dense gas clouds in the IGM organize themselves and react within much larger 'sheets' or 'pancakes' of matter in the vastness of space.

Dark matter, which researchers believe make up about 80% of the universe?s mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new study now suggests that dark matter may have existed before the Big Bang.

At the center of certain galaxies are objects of such tremendous brightness they outshine the rest of their galaxy by four orders of magnitude. Our understanding of these active galactic nuclei has progressed by leaps and bounds over the past several decades, though recently debate has centered on the identity of some of these objects.

A piping hot planet discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star's habitable zone. If made of rock, this planet may be around twice Earth's size.
