Webb space telescope opens door to discoveries still unimagined

The powerful James Webb Space Telescope's inaugural batch of images has opened a new chapter of cosmic exploration, but astronomers say the observatory's most consequential discoveries may well be those they have yet to even imagine. Read More...

Nasa telescope takes super sharp view of early cosmos

US President Joe Biden, pausing from political pressures to bask in the glow of the cosmos, on Monday released the debut photo from NASA's James Webb Space Telescope - an image of a galaxy cluster revealing the most detailed glimpse of the early universe ever seen. Read More...

NASA to showcase Webb space telescope's first full-color images

Drawing back the curtain to a photo gallery unlike any other, NASA will soon present the first full-color images from its James Webb Space Telescope, a revolutionary apparatus designed to peer through the cosmos to the dawn of the universe Read More...

Webb telescope: NASA to reveal deepest image ever taken of Universe

NASA administrator Bill Nelson said Wednesday the agency will reveal the "deepest image of our Universe that has ever been taken" on July 12, thanks to the newly operational James Webb Space Telescope. Read More...

Three, two, one: astronomers predict SpaceX space junk will hit the Moon

A chunk of a SpaceX rocket that blasted off seven years ago and was abandoned in space after completing its mission will crash into the Moon in March, experts say. The rocket was deployed in 2015 to put into orbit a NASA satellite called the Deep Space Climate Observatory (DSCOVR). Read More...

NASA's new space telescope reaches destination in solar orbit.

NASA's James Webb Space Telescope, designed to give the world an unprecedented glimpse of infant galaxies in the early stages of the universe, arrived at its gravitational parking spot in orbit around the sun on Monday, nearly a million miles from Earth. With a final five-minute, course-correcting thrust of its onboard rocket, Webb reached its destination at a position of gravitational equilibrium known as the second Sun-Earth Lagrange point, or L2, arriving one month after launch, NASA officials said.

NASA begins process of bringing new space telescope into focus

NASA on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer. Mission control engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope's principal mirror.

US man recovering after 'breakthrough' pig-heart transplant

A US man with terminal heart disease was implanted with a genetically modified pig heart in a first-of-its-kind surgery, and three days later the patient is doing well, his doctors reported on Monday. The surgery, performed by a team at the University of Maryland Medicine, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.

Discovery of UK's largest sea dragon among 'greatest' finds

Scientists have hailed one of the "greatest finds" in British paleontological history after the largest fossilised remains of a prehistoric "sea dragon" were discovered in the Midlands. The ichthyosaur, approximately 180 million years old with a skeleton measuring around 10 metres in length and a skull weighing approximately one ton, is the largest and most complete fossil of its kind ever found in the UK.

Webb telescope fully deployed in space: NASA

The James Webb Space Telescope has completed its two-week-long deployment phase, unfolding its huge, gold-plated, flower-shaped mirror panel as it readies to study every phase of cosmic history. Engineering teams cheered back at the Space Telescope Science Institute in Baltimore, Maryland as NASA announced on Twitter that the final portion of the 6.5-meter (21-foot) mirror was deployed. “I’m emotional about it – what an amazing milestone,” Thomas Zurbuchen, a senior NASA engineer, said during the live video feed on Saturday as stargazers worldwide celebrated.

Webb telescope to look for first light of cosmic dawn

Peering into deep space and billions of years back in time, the James Webb telescope promises to offer the clearest glimpse yet of the Universe's cosmic dawn, when the earliest galaxies began to form. The largest and most powerful telescope ever to be launched into space, which will take over from Hubble, will "directly observe a part of space and time never seen before", says NASA. This is the Universe in its youth, just a few hundred million years after the Big Bang. With "very lofty science goals in mind", Webb will look back 13.5 billion years to when the first galaxies evolved in the Universe, said Begonia Vila, instrument systems engineer at NASA's Goddard Space Flight Center in a briefing.

A new book shows how animals are already coping with climate change

‘Hurricane Lizards and Plastic Squid’ offers both good news and bad news Hurricane Lizards and Plastic Squid Thor Hanson As a conservation biologist, Thor Hanson has seen firsthand the effects of climate change on plants and animals in the wild: the green macaws of Central America migrating along with their food sources, the brown bears of Alaska fattening up on early-ripening berry crops, the conifers of New England seeking refuge from vanishing habitats. And as an engaging author who has celebrated the wonders of nature in books about feathers, seeds, forests and bees (SN: 7/21/18, p. 28), he’s an ideal guide to a topic that might otherwise send readers down a well of despair.

Tiny living machines called xenobots can create copies of themselves

Tiny “living machines” made of frog cells can replicate themselves, making copies that can then go on to do the same. This newly described form of renewal offers insights into how to design biological machines that are self-perpetuating. “This is an incredibly exciting breakthrough,” for the field of biologically based robotics, says Kirstin Petersen, an electrical and computer engineer at Cornell University who studies groups of robots. Robots that can copy themselves are an important step toward systems that don’t need humans to operate, she says. Read More...

NASA introduces its 10 'Artemis generation' astronaut candidates

Chosen from over 12,000 applicants, NASA's future astronauts have their hearts set on visiting the moon. Test pilots. Engineers. Physicists. A US National Team cyclist. A SpaceX flight surgeon. On Monday, NASA announced its 2021 class of 10 future astronauts, a diverse group of high achievers. The space agency calls them the "Artemis generation" because they are likely to be heavily involved in future Artemis-program missions to the moon. "The women and men selected for the new astronaut class represent the diversity of America and the career paths that can lead to a place in America's astronaut corps," NASA said in a statement.

Dinosaur Tail Found in Chile Stuns Scientists

Chilean paleontologists on Wednesday presented their findings on a dinosaur discovered three years ago in Patagonia which they said had a highly unusual tail that has stumped researchers The remains of the Stegouros elengassen were discovered during excavations in 2018 at Cerro Guido, a site known to harbor numerous fossils, by a team who believed they were dealing with an already known species of dinosaur until they examined its tail. "That was the main surprise,” said Alexander Vargas, one of the paleontologists. “This structure is absolutely amazing." Read More...
