Led by ESA (European Space Agency) with contributions from NASA, the Euclid space telescope has discovered 31 of the oldest quasars ever documented. In fact, two are the oldest ever observed, dating back to the universe’s infancy, when it was just 5% of its current age. A new study details the results in the journal Astronomy & Astrophysics. A quasar occurs when immense amounts of gas and dust […]
The Sun emitted a strong solar flare, peaking at 4:41 p.m. ET on July 4. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft […]

A mission to raise the orbit of NASA’s Swift observatory has reached orbit.
The launch of Katalyst's robotic servicing spacecraft LINK is now targeted for no earlier than Friday, July 3.
Cartilage repair, cardiac research, and cargo operations wrapped up the week for the Expedition 74 crew before heading into a relaxing three-day weekend. The International Space Station is also orbiting higher following a reboost maneuver on Wednesday.
The launch of Katalyst’s robotic servicing spacecraft LINK on Northrop Grumman’s Pegasus XL rocket was postponed Thursday.
A major update to Eyes on Exoplanets was released on June 11, 2026, complete with a brand-new tutorial. The introductory welcome screen was completely updated, and in a major upgrade, every single star in the app (4,716 stars and counting) now has its own description panel, similar to those of the exoplanets in the application. […]
Four Expedition 74 astronauts had a light duty day on Wednesday following the previous day’s spacewalk for external robotics maintenance. The remaining three crew members from Roscosmos focused on cardiac research and lab maintenance aboard the International Space Station.
