For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the ...
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky ...
Egyptian blue, considered the world's earliest synthetic pigment, was prized for its stable blue hues and served as a common blue paint in Egypt as early as 5,000 years ago, as well as the base material for small items such ...
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
Hold on to your telescopes: The DESI Legacy Imaging Surveys team has released the largest-ever 2D color map of the universe. The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, primarily stars and galaxies. ...
Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to ...
At the top and bottom of the planet, the seasons arrive on a schedule all their own. Satellite data from a mission measuring infrared energy reveal just how differently—and how dramatically—surface temperatures swing across ...
Since it became operational in 2022, the James Webb Space Telescope (JWST) has released some truly breathtaking views of the cosmos. These images highlight how advancements since the days of the venerable Hubble Space Telescope ...
