The debut of Sierra Space’s cargo space plane Dream Chaser has delayed again and will no longer see a docking with the International Space Station. In a statement Thursday afternoon, NASA said the space agency and Sierra Space had agreed to a major modification of their space station resupply contract.
New images from the European Space Agency's Trace Gas Orbiter reveal Mars' atmosphere to have delicate layers of dust and ice, offering insights into the planet's evolution.
Radio astronomy began in the 1930s when Karl Jansky, an engineer at Bell Telephone Laboratories, accidentally discovered radio waves coming from the Milky Way. He was investigating sources of interference in transatlantic radio communications, no-one expected this to be the birth of radio astronomy. The finding opened an entirely new window on the universe, one that could peer through clouds, dust and observe phenomena invisible to optical telescopes. The field really took off after World War II when surplus military radar equipment became available to scientists with major discoveries following rapidly from pulsars to quasars, the cosmic microwave background radiation and the detailed structure of galaxies. Today's radio telescopes, from giant single dishes like the 500 metre FAST telescope in China to vast interferometer arrays like the Square Kilometre Array, continue to revolutionise our understanding of the universe.
The team behind Europe's Euclid space telescope just published the world's most extensive simulation of the universe, which maps an astonishing 3.4 billion galaxies.
The European Space Agency (ESA) is participating in the 76th International Astronautical Congress (IAC), which will open its doors on Monday 29 September and last until Friday 3 October in Sydney, Australia. Over 8000 participants from 90 countries are expected to attend the event at the at the International Convention Centre (ICC) under the theme “Sustainable Space: Resilient Earth”.

A SpaceX Falcon 9 rocket launched two dozen Starlink internet satellites from California this morning (Sept. 26) and then came back to Earth for a landing on a ship at sea.
Modifications to a cargo deal between Sierra Space and NASA may mean the Dream Chaser space plane never reaches the International Space Station.
Scientists have confirmed that the Silverpit Crater in the North Sea was caused by an asteroid impact over 40 million years ago, ending years of controversy over its origin.

Update Sept. 26, 1 a.m. EDT: SpaceX deployed the 24 Starlink satellites.
Katalyst Space Technologies has scored a contract to raise the altitude of NASA's Swift Observatory, which has been hunting for gamma-ray bursts from low Earth orbit for more than two decades.
Rocket propulsion technology has evolved from ancient Chinese gunpowder filled bamboo tubes that shot off into opposing armies to the powerful engines of Saturn V and more recently the Space Launch Vehicle and Falcon 9. The journey progressed through centuries of experimentation by pioneers like Konstantin Tsiolkovsky, Robert Goddard, and Hermann Oberth who laid the foundations for modern rocketry. The space race dramatically accelerated development of new technology, producing the liquid fuelled engines that launched Sputnik, sent humans to the Moon, and built the International Space Station.
Star formation is a fundamental physical process in our Universe. Stars light up the cosmos, and give rise to planets, some of which may support life. While humans have no doubt wondered about stars since prehistoric times, new technological tools like the Milky Way have taken our natural curiosity to a whole new level. Now we can peer inside obscured regions and detect young stars in their dusty cocoons.
The star-forming region called Sagittarius B2 contains half of the galactic center's stars, yet only 10% of the gas.
The names of human ancestors are now on an asteroid map.
How we talk about space exploration shapes the futures we imagine and build.
New JWST observations show Saturn's auroras dotted with dark beads and a star pattern missing two arms, puzzling astronomers.
SpaceX launched 28 of its Starlink internet satellites to orbit from Florida this morning (Sept. 25), on the company's 122nd Falcon 9 mission of the year.
Rather than the fearsome enemies of movies like "The Terminator," as we move into the universe, AIs can be our partners, our children, and perhaps even us.
The Canon RF 85mm f/1.2L USM is a dream lens for many photographers thanks to its focal length and fast maximum aperture but it's a beast in every way.
