NASA’s Transiting Exoplanet Survey Satellite has found two “super-puff” planets in the same system, each one as light as cotton candy. The post Cotton-Candy Exoplanets: Two for the Price of One! appeared first on Sky & Telescope.
An image of the 2024 total solar eclipse Allexxandar/Alamy On 12 August, a total solar eclipse will sweep across parts of Europe and the Atlantic ocean as the moon passes between Earth and the sun, blocking out sunlight. Parts of the US and Africa, along with the entire UK and much of Europe and Canada,…
No done deals Still, HWO will have its work cut out for it. Even if it is lucky enough to detect a promising signal from a planet, Hammel says, the mission’s science team will need to be able to tease out all the relevant information they can to build up a complete picture of what…
NASA’s James Webb Space Telescope has captured the infrared light of numerous features that previously were impossible to see beyond the thick dust of the FS Tau star system. In addition to myriad background galaxies that burst into view like fireworks for the United States’ 250th anniversary celebrations, this image flickers with a number of…
Heads up aurora chasers! The sun has been very busy. After unleashing an X1.1 solar flare on June 30, the sun continued its outburst by firing off 10 M-class solar flares in 24 hours! Several of these eruptions were accompanied by coronal mass ejections (CMEs) that appear to be at least partially Earth-directed. Exactly how…

By measuring the distance to these echoes, they find the outer arms to be up to…
Astronomers may be getting closer to solving a long-standing mystery about the universe’s largest galaxies. Observations from the X-Ray Imaging and Spectroscopy Mission, known as XRISM, are providing new evidence that supermassive black holes could be preventing these giant galaxies from forming as many stars as expected. According to current models, the most massive galaxies…
BELFAST, NORTHERN IRELAND—According to a statement released by Queen’s University Belfast, a 4,000-year-old stone circle has been discovered in Northern Ireland near the Giant’s Ring, an enclosure surrounded by an earthwork bank. A megalithic tomb rests in the center of the Giant’s Ring. “We came across aerial photography of the area and noticed a number…
