According to our current Cosmological models, the Universe began with a Big Bang roughly 13.8 billion years ago. During the earliest periods, the Universe was permeated by an opaque cloud of hot plasma, preventing atoms from forming. About 380,000 years later, the Universe cooled to a temperature of about -270 °C (-454 °F), which converted much of the energy generated by the Big Bang into light. This afterglow is now visible to astronomers as the Cosmic Microwave Background (CMB), first observed during the 1960s.
Before NASA’s TESS (Transiting Exoplanet Survey Satellite) mission launched in 2018, astronomers tried to understand what it would find in advance. One study calculated that TESS would find between 4430 and 4660 new exoplanets during its primary two-year-long mission.
The upper stage of the SpaceX Falcon 9 rocket that launched the DSCOVR satellite in 2015 will arrive violently on the lunar surface just five weeks from now.
An artificial intelligence program suggests there may be hundreds of thousands of meteorites left for scientists to discover in Antarctica and reveals what may be the most likely places to unearth them.
Young stars go through a lot as they’re being born. They sometimes emit jets of ionized gas called MHOs—Molecular Hydrogen emission-line Objects. New images of two of these MHOs, also called stellar jets, show how complex they can be and what a hard time astronomers have as they try to understand them.
Scientists have found "compelling evidence" that Saturn's "Death Star" moon is hiding an ocean just beneath its surface, furthering the search for possible life in our solar system.
