Astronomers study the atmosphere of a nearby cold brown dwarf star Astronomers used the James Webb Space Telescope (JWST) to observe the cool brown dwarf…
For the first time in history, scientists successfully transmitted an energy beam from an orbiting satellite to a ground station
This is important for space solar energy, which has greater energy production potential than stationary solar panels on Earth. Stationary solar panels are not the…
Webb could directly test one of the dark matter theories
What is the relationship between galaxies and dark matter? Many, if not all, galaxies are surrounded by a halo of this mysterious, unknown, but ubiquitous…

This discovery changed scientists’ understanding of the mechanisms by which star clusters form. An international team of astronomers has discovered a giant galaxy in the…
Astronomers at Steward Observatory have discovered a massive protocluster around a super-luminous quasar.
Such objects, detected at high redshifts, could provide important information about the early phases of the Universe.Astronomers have discovered a new massive protocluster around the…
A collapsor plasma jet can slow a black hole’s rotation until it almost stops.
When black holes appear as stars collapse, they momentarily eject jets of material that literally slow their rotation until it stops completely. Most black holes…
A galaxy with stars that are too old has been discovered in a young universe
For seven years, a team of astronomers searched for rare galaxies in the early universe to estimate their age. They finally succeeded. Data was collected…
Gravitational waves provided us with the elements necessary for life 4.7
An international team of physicists compared the results of studies of supernovae and kilonovae with observations from the James Webb Telescope and came to the…
