Astronomers Use Planet-Hunting Satellite To See White Dwarf “Switch On and Off” for First Time

Astronomers have used a planet-hunting satellite to see a white dwarf abruptly switching on and off for the first time. The researchers led by Durham University, UK, used NASA’s Transiting Exoplanet Survey Satellite (TESS) to observe the unique phenomenon. White dwarfs are what most stars become after they have burned off the hydrogen that fuels them. They are…


Scientists Uncover the Mystery of Early Massive Galaxies That Strangely Ran Out of Fuel

New study reveals that early galaxies have no fuel, and something is stopping them from refilling the tank. Early massive galaxies—those that formed in the three billion years following the Big Bang—should have contained large amounts of cold hydrogen gas, the fuel required to make stars. But scientists observing the early Universe with the Atacama Large…


The British army will begin delivering petrol to fuel

NASA has funded a five-year outreach program in association with the Polarimeter to UNify the Corona and Heliosphere (PUNCH), a solar mission led by Southwest Research Institute (SwRI). The PUNCH Outreach Program, also led by SwRI, is collaborating with five planetariums and science centers in four states, plus other multicultural partners in the southwestern United States….
