Astrophysicists with the Event Horizon Telescope (EHT) Collaboration have conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of distant galaxies at a frequency of around 345 GHz. When combined with existing images of supermassive black holes at the hearts of Messier 87
Astronomers using the Murchison Widefield Array in Western Australia have searched for alien signals at a 10 kHz spectral resolution originating from a population of about 2,800 galaxies toward the Vela supernova remnant. This illustration shows what the activities of a Kardashev Type III civilisation might look like – encapsulating the energy of stars by
In a paper published today in the Astronomical Journal, astronomers analyzed the evolution of massive galaxies at redshifts of 4-8 selected from the JWST Cosmic Evolution Early Release Survey (CEERS).

A new genus and species of large theropod dinosaur being named Alpkarakush kyrgyzicus has been discovered in the Middle Jurassic Balabansai Formation in the northern part of the Fergana Depression, Kyrgyzstan.

Physicists from the STAR Collaboration have observed the antimatter hypernucleus antihyperhydrogen-4 — composed of an antihyperon, an antiproton and two antineutrons — in collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) at DOE’s Brookhaven National Laboratory. An artistic representation of antihyperhydrogen-4 created in a collision of two gold nuclei. Image credit: Institute
Historical and ethnographic sources depict use of portable braced shaft weapons, or pikes, in megafauna hunting and defense during Late Holocene millennia in North and South America, Africa, Eurasia and Southeast Asia. Given the predominance of megafauna in Late Pleistocene North America during the centuries when Clovis points appeared and spread across much of the
Latest Upon completion, the Khavda solar park will be the ‘largest’ operational PV project in the world. Image: Adani Group Indian renewable energy giant Adani Green Energy has signed a 5GW, 25-year power purchase agreement (PPA) with the Maharashtra State Electricity Distribution Company (MSEDCL). The power will be produced at the Khavda solar park, a
Breakup of an asteroid passing within Earth’s Roche limit likely formed the debris ring during the middle Ordovician period, according to new research from Monash University. Tomkins et al. suggest that a large chondrite asteroid had a near miss encounter with Earth 466 million years ago, which caused it to break up as it passed
In the Standard Model of particle physics, the masses of the carriers of the weak interaction, the W and Z bosons, are uniquely related. Physics beyond the Standard Model can change this relationship through the effects of virtual particle quantum loops, thus making it of paramount importance to measure these masses with the highest possible
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for at least one object to cross through the inner Solar System per decade. A flyby like this would introduce a wobble into Mars’ orbit, to a degree that today’s technology could
