Direct image of a black hole expelling a powerful jet      (via sciencedaily.com)     Original source 

Astronomers have observed, in one image, the shadow of the black hole at the center of the galaxy Messier 87 (M87) and the powerful jet expelled from it. Thanks to this new image, astronomers can better understand how black holes can launch such energetic jets.

Medium-sized black holes eat stars like messy toddlers      (via sciencedaily.com)     Original source 

In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, intermediate-mass black holes likely devour wayward stars like a messy toddler -- taking a few bites and then flinging the remains across the galaxy.

Astrophysicists reveal the nature of dark matter through the study of crinkles in spacetime      (via sciencedaily.com)     Original source 

Astrophysicists have provided the most direct evidence yet that Dark Matter does not constitute ultramassive particles as is commonly thought but instead comprises particles so light that they travel through space like waves. Their work resolves an outstanding problem in astrophysics first raised two decades ago: why do models that adopt ultramassive Dark Matter particles fail to correctly predict the observed positions and the brightness of multiple images of the same galaxy created by gravitational lensing?

Could this copycat black hole be a new type of star?      (via sciencedaily.com)     Original source 

It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.

2022 Tongan volcanic explosion was largest natural explosion in over a century, new study finds      (via sciencedaily.com)     Original source 

The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study. The 15-megaton volcanic explosion from Hunga Tonga-Hunga Ha'apai, one of the largest natural explosions in more than a century, generated a mega-tsunami with waves up to 45-meters high (148 feet) along the coast of Tonga's Tofua Island and waves up to 17 meters (56 feet) on Tongatapu, the country's most populated island.

New exoplanet discovered      (via sciencedaily.com)     Original source 

Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.

M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core      (via sciencedaily.com)     Original source 

From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.

James Webb Space Telescope images challenge theories of how universe evolved      (via sciencedaily.com)     Original source 

Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.

Lightning strike creates phosphorus material      (via sciencedaily.com)     Original source 

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.
