New measurements taken with the James Webb Space Telescope (JWST) have deepened the scientific controversy of the Hubble tension — suggesting it may not exist at all. For years, astronomers have found that the universe appears to be expanding at different speeds depending on where they look, a conundrum they call the Hubble tension. Some…

The troubled spacecraft is scheduled to undock on Friday for a trip back to Earth while two NASA astronauts will stay in orbit. Leaving behind the two NASA astronauts it took to the International Space Station three months ago, Boeing’s troubled Starliner spacecraft is set to begin its return to Earth on Friday evening. Six…

Hubble Space Telescope (HST), the first sophisticated optical observatory placed into orbit around Earth. Earth’s atmosphere obscures ground-based astronomers’ view of celestial objects by absorbing or distorting light rays from them. A telescope stationed in outer space is entirely above the atmosphere, however, and receives images of much greater brightness, clarity, and detail than do…

National Aeronautics and Space Administration (NASA), independent U.S. governmental agency established in 1958 for the research and development of vehicles and activities for the exploration of space within and outside Earth’s atmosphere. The organization is composed of four mission directorates: Aeronautics Research, for the development of advanced aviation technologies; Science, dealing with programs for understanding…

Black holes aren’t alive, but it turns out that they can have a heartbeat — if they’re consuming enormous amounts of gas. And new research has discovered just how that heartbeat works. When black holes exist in a binary system — sharing an orbit with another star — they can pull in gas from a…

NASA’s Transiting Exoplanet Survey Satellite (TESS) has so far spotted over 7,000 planets around other stars, but only a fraction of them have been confirmed to be real detections — the rest could be intriguing planets awaiting discovery or simply noise. Unfortunately, however, neither TESS nor other professional telescopes have the luxury of time to…

When astronomers combed through an ancient Hindu text known as the Rig Veda, they discovered that it referenced a total solar eclipse that occurred roughly 6,000 years ago — making it the oldest known mention of an eclipse. The Rig Veda, a collection of sayings and hymns from various religious and philosophical schools, was compiled…

WEST GLACIER, Mont. – Glacier National Park will host its first ever Astronomy Week starting Tuesday with events throughout the park featuring activities like solar viewing, night sky programs, and astrophotography workshops. NASA scientists from the James Webb Telescope and NASA Goddard Space Flight Center will be at events during the week. They will share…

What it is: Spiral galaxy NGC 6744 Where it is: 30 million light-years away in the constellation Pavo When it was shared: Aug. 21, 2024 Why it’s so special: Because we’re embedded within the Milky Way and there’s no way of sending spacecraft much further than the solar system’s edge, astronomers have no way of…
