The NASA/ESA's Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away. Supernovae like this one can be used as cosmic tape measures, allowing astronomers to calculate the distance to their galaxies.
ESA's Rosetta mission has revealed a unique kind of aurora, an exciting phenomenon seen throughout the Solar System, at its target comet, Comet 67P/Churyumov-Gerasimenko.
Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves.
New observations by the NASA/ESA Hubble Space Telescope suggest that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse's surface.
Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth's atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life.
New research using data from multiple spacecraft, including ESA's Cluster mission, has revealed the cause behind the sudden brightening of the auroral oval before it breaks up into a substorm.
A global collaboration of telescopes including ESA's INTEGRAL high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy – something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery.
The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed 'campfires', near the surface of our closest star.
Two studies based on ESA's Mars Express observations of Jezero crater, the future landing site for NASA's 2020 Mars Perseverance rover, have shed light on how and when this intriguing area formed – and identified the regions most likely to reveal signs of ancient life.
An observation campaign led by ESA's XMM-Newton space observatory reveals the youngest pulsar ever seen – the remnant of a once-massive star – that is also a 'magnetar', sporting a magnetic field some 70 quadrillion times stronger than that of the Earth.
New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought.
The NASA/ESA Hubble Space Telescope was used to conduct a three-year study of the crowded, massive and young star cluster Westerlund 2. This is the first time that astronomers have analysed an extremely dense star cluster to study which environments are favourable to planet formation.
The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home.
Currently crossing the skies above Earth, Comet C/2020 F8 (SWAN) has the potential to become a more prominent naked eye object by late May or early June. Yet it wasn't discovered by someone looking up at the night sky.
Science instruments aboard the European-Japanese Mercury explorer BepiColombo are in excellent condition to gather high-quality data during the spacecraft's long cruise to Mercury despite not having been designed for this purpose, teams collaborating on the mission learned during the spacecraft's April flyby of Earth.
What astronomers thought was a planet beyond our solar system, has now seemingly vanished from sight. Astronomers now suggest that a full-grown planet never existed in the first place.
Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA's XMM-Newton, NASA's Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong.
New data from the NASA/ESA Hubble Space Telescope have provided the strongest evidence yet for mid-sized black holes in the Universe. Hubble confirms that this "intermediate-mass" black hole dwells inside a dense star cluster.
Using over 18 years of data from ESA's Cluster mission, scientists have mapped the heavy metals in the space surrounding Earth, finding an unexpected distribution and prevalence of iron and shedding light on the composition of our cosmic environment.
The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.
