Multi-Color Pictures of Black Holes By Brian Koberlein May 24, 2025 Astronomers with the Event Horizon Telescope have developed a new way to observe the radio sky at multiple frequencies, and it means we will soon be able to capture color images of supermassive black holes. Continue reading Astronomers Conduct a Preliminary Search for Exoplanets Around Alpha Centauri By Matthew Williams May 23, 2025 An international team of researchers has announced the preliminary findings of Webb’s observations of the Alpha Centauri system. According to their analysis, Webb could detect a Jupiter-sized planet and a very bright zodiacal dust disk around Alpha Cen A. More information will be released soon! Continue reading Is Venus Hiding Dangerous Asteroids? By Evan Gough May 23, 2025 Twenty years ago, the US Congress instructed NASA to find 90% of near-Earth asteroids threatening Earth. They’ve made progress finding these asteroids that orbit the Sun and come to within 1.3 astronomical units of Earth. However, they may have to expand their search since astronomers are now finding asteroids co-orbiting Venus that could pose a threat. Continue reading How To Resolve Conflicts Over Lunar Resources By Andy Tomaswick May 23, 2025 Sometimes, space enthusiasts blind themselves with techno-optimism about all the potential cool technological things we can do and the benefits they can offer humanity. We conveniently ignore that there are trade-offs: if one group gets to utilize the water available on the lunar surface, that means another group doesn’t get to. Recognizing and attempting to come up with a plan to deal with those sorts of trade-offs is the intent of a new paper by Marissa Herron and Therese Jones of NASA’s Office of Technology, Policy, and Strategy, as well as Amanda Hernandez of BryceTech, a contractor based out of Virginia. Continue reading More Questions About Life on Exoplanet K2-18b By Evan Gough May 23, 2025 Whenever scientists present new research showing potential biosignatures on an exoplanet, follow-up articles spread like ripples on a pond. Mainstream media usually runs with it, which shows how the issue captures people’s attention. The issue of life on other worlds is a compelling one. This is what happened recently with the exoplanet K2-18b. Continue reading Venus Has a Single Solid Crust... But It’s Surprisingly Thin By David Dickinson May 23, 2025 Our nearest neighbor is only slightly smaller than the Earth… but that’s just about the only thing the two planets have in common. Now, a recent NASA-funded study suggests that the interior of Venus may be equally strange as well. Continue reading HERMES-PF’s 6 CubeSats Watch The Entire Sky For High-Energy Bursts By Andy Tomaswick May 22, 2025 Multi-messenger astronomy has been all the rage lately. It involves capturing data on the gravitational and electromagnetic signals from catastrophic cosmic events. However, with that newfound interest comes required updates to infrastructure. Gravitational wave detectors have been upgraded and will be even more sensitive soon. But to realize the promise of multi-messenger astronomy, scientists must have a fleet of spacecraft watching the entire sky for high-energy signals indicative of the events that cause gravitational waves. At least, that is the team’s long-term plan behind the High Energy Rapid Modular Ensemble of Satellites Pathfinder (HERMES-PF) mission, which successfully launched in March and is currently undergoing commissioning. Continue reading Our Solar System May Have a New Planetary Sibling: Another Dwarf Planet By Evan Gough May 22, 2025 Our understanding of our Solar System is still evolving. As our telescopes have improved, they’ve brought the Solar System’s deeper reaches into view. Pluto was disqualified as a planet because of it. Now, new research says another dwarf planet may reside at the edge of the Solar System. Its presence supports the Planet X hypothesis. Continue reading Mapping the Center of the Milky Way in 3D By Mark Thompson May 22, 2025 The Solar System is a whopping 26,000 light-years from the heart of the Milky Way, where a mysterious and dense region—shrouded in thick gas and dust—holds one of the Galaxy’s most active zones: the Central Molecular Zone (CMZ). A team of scientists have unleashed a cutting-edge 3D model of this region, mapping out everything from massive molecular clouds to young stars in the making. Armed with powerful radio telescopes and infrared observatories, they’ve pieced together a detailed map, offering a rare glimpse into the heart of our Galaxy’s chaotic core. Continue reading The Location of a Galaxy’s Gas Plays a Role in Star Formation By Mark Thompson May 22, 2025 Galaxies are stellar factories generating stars at different speeds—some working at a breakneck pace while others trickling along! We have known for a long time that the availability of raw materials makes a difference to stellar formation, but according to a new paper which surveyed 1,000 galaxies the location of the matter plays a role too. Those with a high stellar formation rate seem to have a high volume of gas reserves in the heart of their densest star clusters with the highest concentration of stars.
