Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere.
Astronomers using NASA's Hubble Space Telescope have found a rare fast radio burst (FRB). This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date.
The telescope had paused science observations Nov. 23 due to an issue with one of its gyros. The spacecraft is in good health and once again operating using all three of its gyros.
The chances of finding extraterrestrial life have improved slightly after NASA announced that its Hubble Space Telescope has confirmed the size of an Earth-sized exoplanet only 22 light-years from Earth.
A new method for scanning telescope images for the faintest signs of rock far beyond Pluto has uncovered evidence that our Solar System's disc of material extends far further into interstellar space than we thought.
A very rare, strange burst of extraordinarily bright light in the universe just got even stranger. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto the scene where it wasn't expected to be found.
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.
For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.
NASA engineers are optimistic they’ll be able resolve a problem with the Hubble Space Telescope’s payload computer that knocked the observatory out of action on 13 June.
FRBs are powerful jets of energy that has mysterious origins. The research team performed a survey of eight FRBs, from which they were able to determine that five of them originated from a spiral arm in their host galaxies.
Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.
Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the Andromeda galaxy and as far as 2 million light-years in some directions.
Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years, different to the value of 13,8 billion years.
The red dwarf Proxima Centauri, just 4.2 lights years away. Recently, U.S. astronomers using data collected from the Hubble Space Telescope 25 years ago, have confirmed the presence of an exoplanet Proxima Centauri c.
The Hubble Space Telescope has captured two images showing Atlas, originally up to 180 metres across, has broken into as many as 30 pieces, each about the size of a house.
