Spiral galaxy pair NGC 4302 and NGC 4298

In celebration of the 27th anniversary of the launch of NASA’s Hubble Space Telescope on April 24, 1990, astronomers used the legendary telescope to take a portrait of a stunning pair of spiral galaxies. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer.

Large number of dwarf galaxies discovered in the early universe

Researchers have found a large population of distant dwarf galaxies that could reveal important details about a productive period of star formation in the universe billions of years ago. It is believed that dwarf galaxies played a significant role during the so-called reionisation era in transforming the dark early universe into one that is bright, ionised and transparent.

Hubble’s multispectral view of spiral galaxy NGC 3274

This image of the spiral galaxy NGC 3274 comes courtesy of the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3). Hubble’s WFC3 vision spreads from the ultraviolet light through to the near infrared, allowing astronomers to study a wide range of targets, from nearby star formation through to galaxies in the most remote regions of the cosmos.

Hubble views supernova shrapnel

Several thousand years ago, a star some 160,000 light-years away from us exploded, scattering stellar shrapnel across the sky. The aftermath of this Type Ia supernova is shown here in this striking image from the NASA/ESA Hubble Space Telescope. The exploding star was a white dwarf located in the Large Magellanic Cloud, a close neighbouring galaxy.

Hubble sees the shredded remains of a supernova

This NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star. These rippling wisps of ionised gas, named DEM L316A, are the remains of an especially energetic Type Ia supernova located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbours — the Large Magellanic Cloud (LMC).

Hubble nets a cosmic tadpole

This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious properties — with interesting results.

Cloudy days on exoplanets may hide atmospheric water

Water is a hot topic in the study of exoplanets, including “hot Jupiters” close to their parent stars that can reach a scorching 1,100 °C, meaning any water they host would take the form of vapour. Hot Jupiters have been found with water in their atmospheres, but others appear to have none. NASA scientists wanted to find out what the atmospheres of these giant worlds have in common.
