- Chandra Spots Possible Supernova Remnant Near Galactic Center — NASA
X-ray data from Chandra reveal a candidate supernova remnant in the Milky Way’s central region. If confirmed, the remnant would rank among the closest known to the galaxy’s supermassive black hole. The detection relies on extended X-ray emission matching expected signatures from an exploded star’s debris. Confirmation would require additional multi-wavelength observations to distinguish it from other energetic processes near the black hole. Astronomers will next compare the feature against archival Chandra and radio datasets for structural details.

An ultra-high-energy neutrino has been linked to a galaxy whose jets point away from our line of sight. Researchers combined IceCube neutrino detections with radio and gamma-ray observations to identify the source. The galaxy’s misaligned jets still produce neutrinos through interactions in dense surrounding material. This detection adds to evidence that such “shadow blaster” systems contribute to the cosmic neutrino flux. Follow-up monitoring will search for additional neutrinos from the same direction.

The Mars Express orbiter captured dozens of dust devils across the Mamers Valles region. These whirlwinds appear as dark streaks or bright plumes against the surface in high-resolution images. The observations help map local wind patterns and dust lifting processes in a mid-latitude valley system. Repeated imaging passes allow scientists to track how frequently these vortices form. Future orbits will target seasonal changes in devil activity. Source: esa.int - Webb Observes Extreme Heating on Hot Jupiter — r/space
JWST measured dayside temperatures on a hot Jupiter exceeding earlier model predictions. The data show intense stellar irradiation driving atmospheric circulation and heat redistribution. Spectral features indicate varying cloud cover and chemistry across the planet’s hemispheres. Researchers are comparing these results against circulation models to refine temperature and wind forecasts. Additional JWST phase-curve observations are planned for similar planets.

Observers across parts of North America can watch the Moon occult Venus on June 17. The event occurs as the Moon travels eastward along the ecliptic. Venus will disappear behind the lunar disk for several minutes depending on location. Binoculars or small telescopes will show the planet’s thin crescent phase just before and after the occultation. Clear skies near local sunset offer the best viewing window. Source: astronomy.com - NASA Plans Mission to Raise Swift Observatory’s Orbit — Space.com
A dedicated spacecraft will rendezvous with the Neil Gehrels Swift Observatory this summer. The goal is to boost the telescope to a higher altitude and extend its operational life. Swift has provided rapid multi-wavelength follow-up of gamma-ray bursts and other transients since 2004. Engineers have developed a docking and propulsion system specifically for this first-of-its-kind servicing attempt. A press conference today will outline the timeline and technical approach.

Observations of a nearby ultra-hot rocky planet reveal a thick hydrogen envelope replenished by volcanic outgassing. Extreme stellar heating drives continuous melting of the surface and release of volatiles. Spectral data indicate the atmosphere remains dynamically active rather than escaping entirely. The planet serves as a laboratory for studying magma-ocean worlds at close orbital distances. Additional infrared measurements will track changes in atmospheric composition over time.

A new analysis concludes that only a tiny fraction of the volume inside Earth’s orbit has been surveyed for possible alien artifacts. The five human-built interstellar probes demonstrate that technological civilizations can launch objects on escape trajectories. Researchers outline strategies using existing and near-future surveys to improve coverage. They emphasize that non-detection so far does not rule out the presence of such objects. Expanded infrared and visible searches are recommended. Source: phys.org - Webb and Hubble Clarify Nature of Terzan 5 — phys.org
Combined observations show Terzan 5 is the remnant of an accreted dwarf galaxy rather than a classic globular cluster. Hubble provided precise proper-motion measurements while Webb supplied infrared views of its stellar populations. The cluster contains stars with a wide range of ages and metallicities consistent with galactic building blocks. These findings refine models of how the Milky Way assembled through mergers. Further spectroscopy will map chemical abundance patterns across the system. Source: phys.org - Cold Atom Lab Receives Upgrade on Space Station — phys.org
Astronauts activated an enhanced version of NASA’s Cold Atom Lab aboard the ISS. The facility now reaches lower temperatures and supports longer observation times for quantum gases. Microgravity allows researchers to study Bose-Einstein condensates without gravitational sag that limits ground experiments. New capabilities will probe fundamental questions in quantum mechanics and atom interferometry. Data from the upgraded instrument are expected within weeks.

Cosmic Spotlight
Chandra’s candidate supernova remnant sits only a few light-years from Sagittarius A*, offering a rare nearby example of stellar death in the galactic center’s harsh environment. The extended X-ray glow matches expectations for shock-heated gas from an explosion that occurred thousands of years ago. Multi-wavelength follow-up could reveal whether the remnant is interacting with the dense molecular material or the black hole’s outflow. Confirmation would help calibrate models of supernova rates and feedback near supermassive black holes. How many more such remnants remain hidden in the crowded central parsecs?
Cosmic Deep Dive: How Neutrinos Slip Through Matter
A single neutrino could cross a block of lead one light-year thick and emerge on the other side with barely any chance of interacting. These ghostly particles interact only through the weak force and gravity, so ordinary matter presents almost no obstacle. In the Sun’s core, trillions of neutrinos stream outward every second; on Earth we detect only a handful per cubic centimeter each second despite the flood passing through our bodies. Detectors like IceCube bury thousands of photomultiplier tubes deep in Antarctic ice to catch the rare flashes produced when a neutrino finally does collide with an atom. The same elusive nature that makes them hard to catch also lets them carry undistorted information from the most violent cosmic events across billions of light-years. Yet physicists still cannot explain why neutrinos have any mass at all, or why their three flavors oscillate in ways that challenge the simplest versions of the Standard Model.
