Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis

NASA’s Hubble Space Telescope has provided new insights into the young star FU Orionis, located in the constellation Orion. Observations have uncovered extreme temperatures in the inner region of its accretion disk, challenging current models of stellar accretion. Using Hubble’s Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph, astronomers captured far-ultraviolet and near-ultraviolet spectra, revealing […]

How a Hubble scientist draws on her elite athletic career to advance space exploration

The cosmos may feel totally inaccessible to the average human, that reminder of an infinite expanse that looks cool to everyone but can only be understood by solitary geniuses.  Julia Roman-Duval sees outer space differently. The astronomer at the Space Telescope Science Institute (STScI), the Johns Hopkins– and Hampden-headquartered operations center for NASA’s top telescopes, […]

Hubble Takes a Look at Tangled Galaxies – NASA Science

The Coma Cluster is a particularly rich cluster that contains over a thousand known galaxies. Amateur astronomers can easily spot several of these in a backyard telescope (See Caldwell 35). Most of them are elliptical galaxies, and that’s typical of a dense galaxy cluster like the Coma Cluster: many elliptical galaxies form through close encounters […]

Hubble Captures a Galaxy with Many Lights – NASA

This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two […]

Hubble Sees a Celestial Cannonball – NASA

The spiral galaxy in this NASA/ESA Hubble Space Telescope image is IC 3225. It looks remarkably as if it was launched from a cannon, speeding through space like a comet with a tail of gas streaming from its disk behind it. The scenes that galaxies appear in from Earth’s point of view are fascinating; many seem to hang […]
