The Jellyfish Nebula (officially known as IC 443) is a supernova remnant about 5,000 light years from Earth. Astronomers have been looking for the spinning neutron star, or pulsar, from the explosion that created the remnant. New Chandra observations have Read More …
This new study helps reveal what happens to supermassive black holes when three galaxies merge together. This result, which used data from NASA’s Chandra X-ray Observatory and several other telescopes, tells astronomers more about how galaxies and the giant black Read More …
A pulsar is a highly magnetized rotating compact star (usually neutron stars but also white dwarfs) that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing Read More …
In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA’s Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits Read More …
Using data from the eROSITA X-ray telescope aboard the Spektrum-Roentgen-Gamma (SRG) observatory, astronomers have detected a previously unknown supercluster of galaxies. The newly found structure consists of eight galaxy clusters. A supercluster is a large group of smaller galaxy clusters Read More …
China has successfully launched a space telescope to study some of the most energetic events in the Universe. Lifting off in December 10th 2020 from the Xichang Satellite Launch Center, the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM, also Read More …
Some of the most stunning views of our sky occur at sunset, when sunlight pierces the clouds, creating a mixture of bright and dark rays formed by the clouds’ shadows and the beams of light scattered by the atmosphere. Astronomers Read More …
A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards the observer. Relativistic beaming of electromagnetic radiation from the jet makes Read More …
Extraordinarily long threads of hot gas known as intergalactic filaments connect and surround galaxies and galaxy clusters throughout the cosmos — and scientists just discovered the longest one yet. The intergalactic filaments make up a cosmic web that stretches across Read More …
#AthenaNuggets 48 deals with Supermassive Black Holes (SMBHs) present in Active Galactic Nucleus (AGN). Its X-ray emission is a unique feature and enables to pierce the inner regions close to the SMBHs. Supermassive black holes are ubiquitous in the center Read More …
