James Webb telescope's mirrors fully deployed

After successfully unfolding the James Webb Space Telescope’s sunshade and optical elements, scientists and engineers are now ready to begin a multi-step process to align the primary mirror’s 18 hexagonal segments.

James Webb Space Telescope finally on its way to discovery

A powerful European Ariane 5 rocket boosted NASA’s $10 billion James Webb Space Telescope into space on Christmas Day, kicking off a great attempt to capture light from the first galaxies to form in the aftermath of the Big Bang.

In a first, ALMA spies huge moon-forming disc around exoplanet

Astronomers using the Atacama Large Millimeter Array (ALMA) have spotted presence of a disc around a Jupiter-like exoplanet 400 light years away that could provide the raw material for up to three satellites the size of Earth’s Moon.

NASA optimistic about Hubble repair, but more time needed

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. 

New "Test-bed" telescope joins hunt for threatening asteroids

Working alongside its northern-hemisphere partner telescope, the ESAs Test-Bed Telescope 2 (TBT2) at La Silla Observatory in Chile will keep a close eye on the sky for asteroids that could pose a risk to Earth.

First X-rays from Uranus discovered

Astronomers have detected X-rays from Uranus using NASA's Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.

Image Of A Black Hole With A Magnetic Field

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light.

Groundbreaking discoveries of the Collapsed Arecibo

The instrument platform of the 305-meter telescope at Arecibo Observatory in Puerto Rico collapsed overnight earlier this week. Its legacy includes discovery of the first pulsars, first exoplanets and first ever radar map of Venus.

Direct evidence of volcanic impact on Io's atmosphere

Previous research has shown that Io's atmosphere is dominated by sulfur dioxide gas. Now, astronomers could, for the first time, clearly see the plumes of sulfur dioxide (SO2) and sulfur monoxide (SO) rise up from the volcanoes.

Europe's largest Solar Telescope GREGOR

GREGOR, the largest solar telescope in Europe, has obtained unprecedented images of the fine-structure of the Sun. Now, the Sun can be observed at a higher resolution than before from Europe.

Hubble maps giant halo around Andromeda Galaxy

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.

Actual Picture of Multiple Planets Orbiting a Star

Direct images of exoplanets are pretty rare. This is the first direct image of multiple exoplanets orbiting a star similar to our Sun taken by The European Southern Observatory’s Very Large Telescope (VLT).

New research of oldest light confirms age of the universe

Recently scientists suggested that have suggested the universe may be hundreds of millions of years younger. However a new observations suggest the universe is still about 13.8 billion years old.

Hubble at 30: A cosmic legacy

30 years ago the Hubble Space Telescope blasted off the launch pad aboard the space shuttle Discovery, ushering in a new era for astronomy that has transformed our understanding of the Universe around us.

The Cheops space telescope is ready to study exoplanets

Cheops (Characterising Exoplanet Satellite), the satellite for the study of the exoplanets of the European Space Agency (Esa), has passed the exams and now it is ready to go to work.
