NASA is contributing to the European Space Agency mission, which will complement dark energy studies by the agency’s upcoming Nancy Grace Roman Space Telescope. The ESA (European Space Agency) Euclid spacecraft lifted off from Cape Canaveral Space Force Station in Florida at 11:12 a.m. EDT on Saturday, July 1, beginning its mission to study why …

The farewell flight of Europe’s workhorse Ariane 5 rocket, scheduled for Tuesday, has been postponed for 24 hours due to bad weather, operator Arianespace said. The 117th and final flight of an Ariane 5 rocket, after 27 years of launches, had been due to take off between 2130 and 2305 GMT from Europe’s spaceport in …

Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a hazy band of stars stretching from horizon to horizon. For the first time, the IceCube Neutrino Observatory in Antarctica has produced an image of the Milky Way using neutrinos—tiny, ghost-like astronomical messengers. In research published June …
Our Milky Way galaxy is an awe-inspiring feature of the night sky, viewable with the naked eye as a horizon-to-horizon hazy band of stars. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrinos—tiny, ghostlike astronomical messengers. In an article to be published in the journal …
Europe’s Euclid space telescope is scheduled to blast off Saturday on the first-ever mission aiming to shed light on two of the universe’s greatest mysteries: dark energy and dark matter. The launch is planned from Cape Canaveral in Florida at 11:11 am local time (1511 GMT) on a Falcon 9 rocket of the US …

Isaac Newton formulated his theory of gravity as an action at a distance: a planet instantly feels the influence of another celestial body, no matter the distance between them. This characteristic motivated Albert Einstein to develop the famous theory of general relativity, where gravity becomes a local deformation of spacetime. The principle of locality states …

The Euclid mission will focus on illuminating dark matter and dark energy. The ESA (European Space Agency) and SpaceX are targeting no earlier than 11:11 a.m. EDT (8:11 a.m. PDT) Saturday, July 1, to launch the Euclid spacecraft. Euclid is an ESA mission with contributions from NASA that will shed light on the nature of …

Observations by NASA’s NuSTAR X-ray telescope give astronomers new clues about the brightest and most energetic gamma-ray burst ever detected. When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more …

While searching for the origins of a powerful gamma-ray burst (GRB), an international team of astrophysicists may have stumbled upon a new way to destroy a star. Although most GRBs originate from exploding massive stars or neutron-star mergers, the researchers concluded that GRB 191019A instead came from the collision of stars or stellar remnants in …

Using the Hubble Space Telescope (HST) and Jansky Very Large Array (VLA), astronomers have investigated an ultra-diffuse galaxy known as UGC 9050-Dw1. Results of the study, published June 9 on the pre-print server arXiv, yield important insights into the properties of this galaxy. Ultra-diffuse galaxies (UDGs) are extremely-low-density galaxies. The largest UDGs have sizes similar …
