Nearly three years since launch, Webb is a hit among astronomers
From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther than human eyes have ever seen. In May, astronomers announced that Webb detected the most distant galaxy found so far, a fuzzy blob of red light that we see as it existed just 290 million years after…

‘We have a telescope!’ Rubin Observatory construction team installs its huge mirror
The Simonyi Survey Telescope now has its mirrors and a camera in place. (Credit: Rubin Observatory) The Vera C. Rubin Observatory’s 8.4-meter Simonyi Survey Telescope in Chile has now been equipped with all three of its mirrors, plus a camera for good measure. Last week’s installation of the telescope’s combined primary/tertiary mirror represented a major…

“Not a bluff”—NASA’s budget would shut down long-lived Chandra telescope
NASA launched the Chandra X-ray Observatory 25 years ago this week, opening a new eye on the Universe and giving astronomers vision into unimaginably violent cosmic environments like exploding stars and black holes. But Chandra’s mission may soon end as NASA’s science division faces a nearly billion-dollar budget shortfall. NASA says it can no longer…

NASA Selects SpaceX for 2027 Launch of Gamma-Ray Astronomy Mission
NASA has chosen SpaceX to launch the Compton Spectrometer and Imager (COSI) spacecraft, a small gamma-ray astronomy mission, in August 2027, the agency announced on July 2. The contract, valued at approximately $69 million, includes launch services and related activities. “The agency could not release details on the number of companies that bid on the…

UN Committee to Probe Satellite Constellation Threat to Astronomy, Overcoming Past Setback
The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) has greenlit a pioneering move to scrutinize the looming risks that satellite constellations pose to astronomy, a year subsequent to a thwarted similar endeavor. Marking a pivotal stride in diplomatic avenues concerning celestial research, COPUOS, in a recent session of its scientific and…

The Unistellar Odyssey smart telescope made me question what stargazing means
It’s been 300 years since Galileo and Isaac Newton started fiddling around with lenses and parabolic mirrors to get a better look at the heavens. But if you look at many of the best amateur telescopes today, you’d be forgiven for thinking they haven’t progressed much since. Though components have certainly improved, the basic combination…

Three options for seeing the solar eclipse, from expensive to iffy to absolutely free
Skywatchers gather at Seattle’s Gas Works Park to watch the progress of 2017’s solar eclipse. (GeekWire Photo) After a seven-year gap, a total solar eclipse is once again due to make a coast-to-coast run across North America, boosting popular interest (and airfares) to astronomical proportions. The track of totality for the April 8 eclipse doesn’t…

New app always points to the supermassive black hole at the center of our galaxy
On Thursday, designer Matt Webb unveiled a new iPhone app called Galactic Compass, which always points to the center of the Milky Way galaxy—no matter where Earth is positioned on our journey through the stars. The app is free and available now on the App Store. While using Galactic Compass, you set your iPhone on…

LIGO goes to space: ESA to proceed with LISA gravitational wave detector
On Thursday, the European Space Agency’s Science Programme Committee gave the go-ahead to the Laser Interferometer Space Antenna, or LISA project. This would mean the construction of the mission’s three spacecraft could begin as early as a year from now. While the interferometer would follow the same basic principles as the ground-based LIGO (Laser Interferometer…

Amazon’s Project Kuiper satellites add to astronomers’ light-pollution woes
Amazon is set to launch two satellite prototypes for its Project Kuiper network, which will eventually number more than 3,200 orbiters. Project Kuiper could become a rival to SpaceX’s Starlink constellation, which is now nearly 4,800 strong. Amazon’s launch is planned for 2 pm Eastern time today, with a backup launch window tomorrow. This rapid…
