We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is remarkable, but they might be the only black holes we can observe. That is, unless we take radio astronomy to a whole new level. Go to Source It’s one of astronomy’s great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland’s Maynooth University (MU) and reported today in Nature Astronomy. Go to Source Baby pictures are some of a family’s most cherished artifacts. The same thing can be said of the Hubble Space Telescope and the infant stars it immortalizes in its scientific portraits. But while we know how babies are conceived and how they form in great detail, the same can’t be said for star formation. Go […] To land on the right foot on the Red Planet, European engineers have been dropping a skeleton of the four-legged ExoMars descent module at various speeds and heights on simulated Martian surfaces. Go to Source Astronomers from the National Research Institute of Astronomy and Geophysics (NRIAG) in Cairo, Egypt, have investigated a young open cluster known as Czernik 38. As a result, they found a new open cluster, which turns out to be a companion to Czernik 38. The discovery was detailed in a paper published Jan. 14 on the […] How can scientists estimate the pH level of Enceladus’ subsurface ocean without landing on its surface? This is what a study recently posted to the arXiv preprint server hopes to address as a team of scientists from Japan investigated new methods for sampling the plumes of Enceladus and have provided more accurate measurements of its […] Buzz Aldrin, the second man and only one of 12 to ever walk on the moon, turns 96 today. He’s just one of four living moonwalkers and the oldest remaining astronaut still making trips around the sun. Go to Source Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation and other harmful high-energy particles. Go to Source Back in the earlier days of the internet, there was a viral video from a creator called Bill Wurtz called “the history of the entire world, i guess” which spawned a number of memorable memes, some of which are still in use to this day. One of those was a clip from the video where […] After more than 10 years in orbit, the first Copernicus Sentinel-2 satellite, Sentinel-2A, is still finding new ways to contribute to Earth observation. With its younger siblings, Sentinel-2B and Sentinel-2C, now leading the mission’s core task of delivering high-resolution, ‘camera-like’ images of Earth’s surface, the European Space Agency is pushing Sentinel-2A beyond its original remit. […] Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation in the interstellar medium (ISM). The Chinese National Antarctica and Arctic Research Expedition (CHINARE) has managed to complete a study at Dome A—the highest ice dome on the Antarctic Plateau—and successfully collected submillimeter data […] Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must capture cosmic signals at exactly the same time, acting as a single unit. Research teams at KAIST have developed a new reference signal technology that uses […] SpaceX is starting to get the ball rolling on its Florida launch card with its fourth mission of the year coming less than two days since the last launch, setting a record for its Cape Canaveral launch pad. Go to Source One of the most vivid portraits of “reborn” black hole activity—likened to the eruption of a “cosmic volcano” spreading almost 1 million light-years across space—has been captured in a gigantic radio galaxy. Go to Source Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The newly detected supernova, named SN Eos, exploded when the universe was only 1 billion years old. The finding was reported January 7 on the arXiv pre-print server. Go to Source |
