Hubble observes source of gravitational waves for the first time

(ESA/Hubble Information Centre) The NASA/ESA Hubble Space Telescope has observed for the first time the source of a gravitational wave, created by the merger of two neutron stars. This merger created a kilonova -- an object predicted by theory decades ago -- that ejects heavy elements such as gold and platinum into space. Show More Summary

Image: Hubble's compact galaxy with big-time star formation

As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as ESO 553-46 imaged here by the NASA/ESA Hubble Space Telescope, can produce stars at a hair-raising rate. Show More Summary

Bursting with starbirth

(ESA/Hubble Information Centre) This oddly shaped galactic spectacle is bursting with brand new stars. The pink fireworks in this image taken with the NASA/ESA Hubble Space Telescope are regions of intense star formation, triggered by a cosmic-scale collision. The huge galaxy in this image, NGC 4490, has a smaller galaxy in its gravitational grip and is feeling the strain.

First hints of water detected on Earth-sized TRAPPIST-1 planets

Water could be present on some of the Earth-sized planets orbiting the dwarf star TRAPPIST-1, according to work from an international group of astronomers. They utilized the NASA/ESA Hubble Space Telescope to estimate substantial amounts of water could be present in the outer planets, including three in the habitable zone. This boosts the possibility those planets are livable.[...]

Hubble delivers first hints of possible water content of TRAPPIST-1 planets

(ESA/Hubble Information Centre) An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbour substantial amounts of water. Show More Summary

Image: Section of Hubble solar wing

A deceptively valuable wall hanging: this section of the NASAESA Hubble Space Telescope's solar array flew for eight years in space before being returned to Earth aboard a Space Shuttle, and is now displayed at ESA's technical centre in Noordwijk, the Netherlands.

Hubble displays a dwarf spiral galaxy

The subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth—it sits at a distance of around 44 million light-years from us, placing it within the Milky Way's cosmic neighborhood—NGC 5949 is a perfect target for astronomers to study dwarf galaxies.

Half Of Our Galaxy Might Have Come From Other Galaxies

Image Credit. NASA, ESA, Hubble Space Telescope; Processing. Douglas Gardner Any Carl Sagan fan knows you're made of star stuff. Protons don't decay into any other particles (as far as we can tell), so you can reliably assume that most bits of you have been around since a second after the Big Bang. Show More Summary

Galactic David and Goliath

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Show More Summary

Image: Hubble's galaxy NGC 4242

Tucked away in the small northern constellation of Canes Venatici (The Hunting Dogs) is the galaxy NGC 4242, shown here as seen by the NASA/ESA Hubble Space Telescope. The galaxy lies some 30 million light-years from us. At this distance...Show More Summary

Hubble spots a barred lynx spiral

Discovered by British astronomer William Herschel over 200 years ago, NGC 2500 lies about 30 million light-years away in the northern constellation of Lynx. As this NASA/ESA Hubble Space Telescope image shows, NGC 2500 is a particular kind of spiral galaxy known as a barred spiral, its wispy arms swirling out from a bright, elongated core.

Hubble eyes a powerful galaxy with a password name

(NASA/Goddard Space Flight Center) Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by the NASA/ESA Hubble Space Telescope is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843.

Image: A stormy stellar nursery

This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud.

Hubble 'traps' a vermin galaxy

The NASA/ESA Hubble Space Telescope is famous for its jaw-dropping snapshots of the cosmos. At first glance this Picture of the Week appears to be quite the opposite, showing just a blur of jagged spikes, speckled noise, and weird, clashing colors—but once you know what you are looking at, images like this one are no less breathtaking.

Hubble catches a galaxy duo by the 'hare'

This image from the NASA/ESA Hubble Space Telescope shows the unusual galaxy IRAS 06076-2139, found in the constellation Lepus (The Hare). Hubble's Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments observed the galaxy from a distance of 500 million light-years.
