Astrophysicists make observations consistent with the predictions of an alternative theory of gravity
An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton’s laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now been published in…

Stellar explosion in 1054 C.E. may have been a third flavor of supernova
Astronomers have found convincing evidence that supernovae come in a third flavor, powered by a long-suspected explosive mechanism that may explain a bright supernova humans observed 1,000 ago and that birthed the beautiful Crab Nebula.The evidence is an exploding star observed in 2018, the first that fits all six criteria for a hypothesized type of…

Peculiar planetary system architecture around three Orion stars explained
Peculiar planetary system architecture around three Orion stars explained Not only has the discovery of eoxplanets throughout our galaxy provided a host of new worlds for astronomers to catalogue and observe, but also thrown up new challenges about their formation. New work published in Science by an international team including Carnegie’s Jaehan Bae could explain…

The First Gamma-Ray Pulsar Confirmed by the People
The First Gamma-Ray Pulsar Confirmed by the People Gamma ray pulars werep discovered a little while ago, and in onepone family, the spider pulsar, it accretes or gains matter from a nearby companion star in much the same way some spiders eat their mates. In this “Black Widow” type of spider pulsar the…

Stream of local stars formed in another galaxy is evidence of The Milky Way’s violent history
A Vast Stream of Flowing Stars Is Evidence of The Milky Way’s Violent History Using data from the Gaia Milky Way mapping survey, astronomers have discovered a vast stream of stars that they believe are the remnants of a massive dwarf galaxy that got dragged into the galactic disc before being torn apart.…

A Pulsed Discovery In Omega Centauri
A Pulsed Discovery In Omega Centauri A recent study has unveiled a new discovery at the heart of globular cluster Omega Centauri: five long-anticipated pulsars. The globular cluster Omega Centauri makes for an impressive sight — millions of stars gravitationally bound into a beautiful sphere, its core alight from the glow of densely packed bodies.…

Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences
Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU…

Black Hole Holograms
Black Hole Holograms A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly…
