It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy. Launched on December 25 last year and fully operational since July, the telescope offers glimpses of the universe that were inaccessible to us before. Like the Hubble Space Telescope, the Webb telescope is in space, so ...
Black holes form natural time machines that allow travel to both the past and the future. But don’t expect to be heading back to visit the dinosaurs any time soon. At present, we don’t have spacecraft that could get us anywhere near a black hole. But, even leaving that small detail aside, attempting to travel ...
The first images of a nebula from the James Webb Space Telescope gave astronomers remarkable insights into the death of the star that created these beautiful haloes of gas and dust. Among the first five image sets from the James Webb Space Telescope (JWST) released in July were a set of remarkably detailed photographs of the Southern Ring Nebula, ...
A recent study, entirely done by researchers at the Instituto de Astrofísica de Canarias (IAC) has produced the most complete analysis to date of the intracluster light, the diffuse and faint light emitted by stars in galaxy clusters that are not gravitationally bound to any galaxy. This result was based on data obtained by the ...
Neutron stars are the densest objects in our universe, except for black holes. As their name suggests, neutron stars are mainly made of neutrons. However, our knowledge about the matter produced during the collision of two neutron stars is still limited. Scientists from Goethe University Frankfurt and the Asia Pacific Center for Theoretical Physics in ...
NASA’s James Webb Space Telescope (JWST) is revealing the universe with spectacular, unprecedented clarity. The observatory’s ultrasharp infrared vision has cut through the cosmic dust to illuminate some of the earliest structures in the universe, along with previously obscured stellar nurseries and spinning galaxies lying hundreds of millions of light-years away. In addition to seeing ...
The famous Pillars of Creation in the Eagle Nebulae — a star nursery — are believed to result from the hydrodynamic instabilities from magnetic fields that form when plasmas are exposed to high-intensity light from neighboring stars. Stretching roughly 4 to 5 light-years, the Pillars of Creation are a fascinating but relatively minor feature of ...
Astronomers agree that planets are born in protoplanetary disks — rings of dust and gas that surround young, newborn stars. While hundreds of these disks have been spotted throughout the universe, observations of actual planetary birth and formation have proved difficult within these environments. Now, astronomers at the Center for Astrophysics | Harvard & Smithsonian have developed ...
The team, which includes astronomers at the University of Birmingham, detected the rocky planets orbiting LP 890-9, a small, cool star located about 100 light-years from Earth. The star, also called TOI-4306 or SPECULOOS-2, is the second-coolest star found to host planets, after the famous TRAPPIST-1. This rare discovery is the subject of a forthcoming publication ...
While observing a newly-dormant galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope (HST), scientists discovered that it had stopped forming stars not because it had used up all of its gas, but because most of its star-forming fuel had been thrown out of the system as it merged with another galaxy. The ...
