The brown dwarf closest to our solar system hosts wind bands and jet streams, according to new analysis of the object's atmosphere. Brown dwarfs are too big to be planets but not quite massive enough to generate fusion, a prerequisite for stellar classification. Though hot in their infancy, brown dwarfs steadily cool as they mature, making them difficult to spot and study. Becaus

To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy. It

Our astronomers have looked nine billion years into the past to find evidence that galaxy mergers in the early universe could shut down star formation and affect galaxy growth. Using a powerful Earth-based telescope they saw that a huge amount of star-forming gas was ejected into the universe by the coming together of two galaxies. The merger created a new galaxy called ID2299 at a t

During a typical year, over a million people visit Yellowstone National Park, where the Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days. Using data from facilities including NASA's Neil Gehrels Swift Observatory and Transiting Exopla

Through the centuries, scientists and non-scientists alike have looked at the night sky and felt excitement, intrigue, and overwhelming mystery while pondering questions about how our universe came to be, and how humanity developed and thrived in this exact place and time. Early astronomers painstakingly studied stars' subtle movements in the night sky to try and determine how our planet moves i

You've heard of Old Faithful, the Yellowstone National Park geyser that erupts every hour or two, a geological phenomenon on a nearly predictable schedule. Now, an international group of scientists who study space have discovered an astronomical "Old Faithful" - an eruption of light flashing about once every 114 days on a nearly predictable schedule. The researchers believe it is a tidal d

The most distant quasar known has been discovered. The quasar, seen just 670 million years after the Big Bang, is 1000 times more luminous than the Milky Way, and is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the Sun. Seen more than 13 billion years ago, this fully formed distant quasar is also the earliest yet discover

The U.S. departments of Defense and Commerce will jointly seek public input on development of 5G communication networks, they announced on Monday. 5G, or fifth generation telecommunications standard for broadband cellular networks, offers higher download speeds and has been of particular interest to the U.S. military prior to its civilian rollout in 2019. The Defense Department r

Linear accelerators, LINACs for short, are devices that accelerate electrons or other sub-atomic particles along a straight line to generate a beam of high energy. LINACs have a variety of commercial uses such as generating X-rays for cargo inspection, medical diagnostics, food sterilization, and even enabling precise external radiation treatments to destroy cancer cells without damaging surroun

When in space, astronauts typically eat dehydrated, nutrient-dense food, but when it comes to longer space missions, that can become a problem as they'll eventually lack nutrients from fresh vegetables. However, one chemical and biomolecular engineering professor will be researching ways astronauts can grow their own fresh vegetables more efficiently while they are on missions. Ying Diao w
