New Study of Comets Provides Insight into Chemical Composition of Early Solar System

Data from 25 comets were compiled to test predictions of solar system formation and evolution.A current research study from the College of Central Florida has discovered solid support that the outgassing of particles from comets could be the outcome of the composition from the start of our solar system.The outcomes were released today in...

Hubble Detects a Jet Blasting From a Star Crash at 99.97% the Velocity of Light

his is an artist's impression of two neutron stars colliding. The smashup between two dense stellar remnants unleashes the energy of 1,000 standard stellar nova explosions. In the aftermath of the collision a blowtorch jet of radiation is ejected at nearly the speed of light. The jet is directed along a narrow beam confined...

James Webb Telescope Has Already Begun Changing Models And Baffling Scientists

“Cosmic Cliffs” in the Carina NebulaAstronomers' beliefs are The famed James Webb SpaceTelescope, released 8 months back and orbiting the sun a million miles from Earth, has begun bringing up several questions for astronomers as its striking images flood in.Unsurprisingly, the telescope has offered some intriguing and exciting observations of the very distant universe....

Pristine Hubble Image Shows an Exciting Exchange Between Two Galaxies

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...

Unusual, Duplicating Radio Signal Near the Facility of the Galaxy Has Scientists Puzzled

It is not a quick radio ruptured, a pulsar, or low-mass star. So what in the heavens is it?Astronomers have found an unusual, repeating radio signal near the center of the Milky Way, and also it differs from any other energy signature ever studied.The center of the Milky Way, as seen by NASA's Chandra,...
