Balloon-launched telescope observations reveal how material falls into the black hole in Cygnus X-1

  • No comments
A team of researchers used the balloon-borne XL-Calibur telescope to measure polarized X-rays from the black hole Cygnus X-1 in unprecedented detail, revealing new clues about how hot material twists and turns.
ASKAP J1832 belongs to a rare group of objects in space that pulsate in radio waves every few tens of minutes, but what makes it unique is its emission in X-rays as well, as detected by NASA's powerful X-ray observatory, Chandra. This is the first time that X-ray signals have been observed from this type of object, known as "long-period radio phenomena." Credit: X-ray: NASA/CXC/ICRAR, Curtin Univ./Z.

A new mystery in the galaxy's sky: a star that emits radio waves and X-rays at an extremely slow rate

  • No comments
A star called ASKAP J1832 pulsates in both radio and X-rays every 44 minutes—a frequency much slower than any pulsar ever recorded. This unprecedented phenomenon hints at a

NASA found a supermassive black hole spinning in the wrong direction

Astronomers have discovered a puzzling cosmic anomaly – a supermassive black hole in the galaxy NGC 5084 that appears completely tilted relative to its galactic structure.
Hypernova shockwave eruptions: Hypernovae are even more violent astronomical phenomena than supernovae, with explosion energies that exceed those of supernovae by more than ten times. These powerful explosions are usually accompanied by powerful jets that create unique shock explosion structures at the poles of the star. The jets not only cause the explosion, but also create strong flow instabilities within the ejected material, which causes further mixing of the star's interior. Recent observational data suggest that the famous supernova 1987A may be associated with a jet explosion, rather than the spherical explosion predicted by previous one-dimensional models.

716 revolutions per second: the fastest spinning neutron star in the Milky Way

Using a telescope on the International Space Station, researchers have discovered a neutron star in the Milky Way that rotates at an incredible 716 times per second - among the fastest ever discovered
Scientists have discovered a large black hole that "hiccups", and emits gas fluxes. Analysis revealed that a small black hole repeatedly punctures the gas disk of the large black hole, causing the perturbations to be released. Strong magnetic fields, north and south of the black hole, shown by the orange cone, shoot the flux up and out of the disk. Each time the small black hole punctures the disk, it emits another star, in a regular periodic pattern. Credit: Jose-Luis Olivares, MIT

An article published in Nature details Franklin's part in discovering the "backbone" of the DNA molecule. However, due to the competition between the groups, she avoided publishing a large part of them herself, as well as Watson and Crick
