As Hubble nears the end of its life, its much more capable successor, the James Webb Space Telescope, named after a former NASA administrator, is being developed at Johns Hopkins University.

The Webb Space Telescope has captured a plume of gas and dust streaming from a star in the making, with a spiral galaxy as a ...

"The universe is filled with a range of three-body systems, including the closest stars to Earth, the Alpha Centauri star system, and we're finding that the Kuiper Belt may be no exception!" ...

The Hubble Space Telescope 's $9.7 billion successor, the James Webb Space Telescope, has finally come together after a delays and cost overruns. The two halves of the next-generation space ...

But although Webb is a successor to Hubble in some ways, with newer technology and the ability to see the universe in even greater detail, it isn’t a replacement. A pair of new images shows why ...

Despite its many achievements, Hubble is likely nearing the end of its life. The telescope is due for its last periodic servicing in May 2009. Its successor, the James Webb Space Telescope ...

There's no problem, however, with what a team of researchers say is likely a stable trio of icy space rocks in the solar system's Kuiper Belt, found using data from NASA's Hubble Space Telescope ...

An ambitious new survey by the Hubble Space Telescope offers the first bird's-eye view of all known dwarf galaxies orbiting the Andromeda galaxy. The data suggests Andromeda had a chaotic past unlike ...

The Hubble Space Telescope captured an image of the spiral galaxy UGC 5460, located 60 million light-years away, which has experienced two recent supernovae: SN 2011ht and SN 2015as.

The two keys to Edwin Hubble's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to ...
