Scientists create “time machine” simulations studying the lifecycle of ancestor galaxy cities. Credit: Scitech Daily.Scientists have produced simulations that directly recreate the complete life cycle of a few of the biggest collections of galaxies observed.Several processes in astrophysics take a very long time, making their evolution tricky to study. A star like our sun...
A composite image of the R Aquarii binary star was recorded by NASA's flying telescope SOFIA. Credit: NASA.NASA's flying telescope SOFIA has been watching a dance between 2 celebrities orbiting each other as they come close to the minute of the eclipse, enabling astronomers to study how both exchange stardust.SOFIA, short for "Stratospheric...

An illustrated view of a black widow pulsar and its stellar companion. The pulsar’s gamma-ray emissions (magenta) strongly heat the facing side of the star (orange). The pulsar is gradually evaporating its partner. Credit: Pixabay/CC0 Public Domain.The flashing of a nearby star has attracted MIT astronomers to a new and mysterious system 3,000 light-years...
Credit: techzle.Astronomers believe they have discovered proof for an incredibly powerful nuclear explosion in space-- one so unique that seeing one like it again is extremely unlikely.The explosion appears to have occurred inside an unusual neutron star found 140,000 light-years from Earth called MAXI J0556-- 332. Neutron stars are the remnant cores of bigger...
As for we presently know, there is a solitary expanding blob of spacetime speckled with trillions of galaxies - that is our Universe. If there are others, forming a multiverse, we have no riveting evidence for their existence.Theories of cosmology, quantum physics, and the very philosophy of science have some issues that could be...
The cosmos is weirder than we knowYou are acquainted with the old saying: the only thing constant is change. However, we would certainly bet many people do not believe that line applies to the real rules of the universe itself. As it appears, however, researchers at Microsoft, along with scientists at Brown University and...
A deadly asteroidA new Phys.org report released on February 25 could have been the plot of 2021's "Don't Look Up," a Netflix original about a potentially deadly asteroid that threatens to strike Earth. However, the good news is it was simply a close call.According to the website, the first observations of an asteroid called...
Arp 282. (ESA/Hubble & NASA, J. Dalcanton, Dark Energy Survey, DOE, FNAL/DECam, CTIO/NOIRLab/NSF/AURA, SDSS, J. Schmidt)The recurring interaction between two galaxies 320 million light-years away has been recorded in a spectacular Hubble picture.They are collectively named Arp 282 in Halton Arp's Atlas of Peculiar Galaxies. They feature a large barred spiral galaxy called NGC 169, approximately 140,000 light-years across, and a considerably...
