Physicists looking for signs of primordial gravitational waves by sifting through the earliest light in the cosmos - the cosmic microwave background (CMB) - have reported their findings: still nothing.
But far from being a dud, the latest results from the BICEP3 experiment at the South Pole have tightened the bounds on models of cosmic inflation, a process that in theory explains several p Groundbreaking findings in hunt for new neutrinos in the universe

Illinois Institute of Technology Associate Professor of Physics Bryce Littlejohn is part of an international team of scientists that has dealt a blow to a popular theory of the existence of a fourth "sterile" neutrino. The groundbreaking research results were announced at Fermi National Accelerator Laboratory today.

We all know that the dinosaurs died in a mass extinction. But did you know that there were other mass extinctions? There are five most significant mass extinctions, known as the "big five," where at least three-quarters of all species in existence across the entire Earth faced extinction during a particular geological period of time.

It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million year. But when will the next one be? Will there be any warning signs?

Satellites provide important data on climate and the environment every day. According to initial tests, new software from RUAG Space can determine the real-time position of a satellite in space ten times more accurately than was previously possible. More accurate positioning data leads to more precise satellite data and helps to avoid space debris.

A team of physicists has discovered how DNA molecules self-organize into adhesive patches between particles in response to assembly instructions. Its findings offer a "proof of concept" for an innovative way to produce materials with a well-defined connectivity between the particles.
The work is reported in Proceedings of the National Academy of Sciences.

A federal agency has yet again pushed back a final decision on whether to allow the construction of a launchpad for commercial rockets in coastal Georgia.
The Federal Aviation Administration plans to release its decision on Spaceport Camden by Dec. 15 rather than this Wednesday, agency spokesman Steve Kulm said. An agency statement cited a delay caused by "ongoing consultation efforts." The final determination was originally expected at the end of July but now has been delayed at least three times.
Camden County, in the southeast corner of Georgia, wants to build the nation's 13th licensed commercial spaceport and has spent nearly 10 years and $10 million pursuing that goal. The FAA in June issued an environmental impact study that concluded building the spaceport would be its "preferred alternative."
That drew pushback from the National Park Service and its parent agency, the U.S. Department of the Interior. In a July 22 letter to the FAA, the Interior Department said a chance of rockets exploding and raining fiery debris onto the federally protected wilderness on Cumberland Island creates an "unacceptable risk.

This timelapse video was made during ESA astronaut Thomas Pesquet’s second mission to the International Space Station, “Alpha”. The camera is setup to take pictures at intervals of two a second, and the pictures are then edited into this video that plays at 25 pictures a second. The video is around 12 times faster than real speed and was recorded on 20 September 2021.
Thomas shared this video on social media with the caption:

NASA and SpaceX on Saturday scrapped plans to send astronauts to the International Space Station after a large mid-Atlantic storm caused weather issues along the flight path.
The Crew-3 launch, which was set to launch Sunday, is now scheduled to take place 1:10 a.m. EDT Wednesday, when weather conditions were expected to be 80% favorable. The NASA astronauts will launch on SpaceX's Crew
