Galaxies rarely live alone. Instead, dozens to thousands are drawn together by gravity, forming vast clusters that are the largest objects in the universe.
"Galaxy clusters are one of the most awe-inspiring things in the universe," said Prof. Emeritus Don Lamb, a University of Chicago astrophysicist and co-author on a new paper published March 9-one that may point the way towards solving a New research discovers link between disparate approaches to quantum gravity

A new study by researchers from the International Centre for Theoretical Sciences (ICTS) and the Perimeter Institute for Theoretical Physics (PI) discovers a unifying thread in two approaches to quantum gravity that were previously believed to be separate.
Finding a theory of quantum gravity - which would combine both quantum mechanical and gravitational effects - is one of the great unsol Fleet Space Technologies teams up with Seven Sisters Consortium

Buzz Aldrin's famous 1969 moon walk picture sells at auction
Wednesday, 09 March 2022 18:42 Write a comment
More than 70 original NASA photographs including a celebrated image of Buzz Aldrin's moon walk taken by Neil Armstrong were sold at auction in Copenhagen on Wednesday for more than 155,000 euros ($172,000).
The Aldrin image, which fetched 5,373 euros, shows the astronaut on the surface of the moon in July 1969 during the first manned lunar landing. It was famously used on the cover of LIFE magazine.
Armstrong, the first man to step onto the Moon, can be seen in the reflection of Aldrin's visor.
A total of 74 NASA photographs were put up for sale including 26 taken on the Moon during the Apollo missions in the 1960s and 1970s.

Join ESA astronaut Matthias Maurer on a tour of Columbus, Europe’s science laboratory on the International Space Station.
Cosmic Kiss is Matthias’s first mission to the Space Station and the Columbus module is one of his main workplaces. It is also where he sleeps in his crew quarters known as CASA.
Columbus is Europe's largest contribution to the orbital outpost and the first European laboratory for permanent, multidisciplinary research in space. It houses 16 standardised payload cabinets, known as racks, which host laboratory equipment and technical systems. This allows the facility to support research across a wide range of

How to talk to extraterrestrials
Wednesday, 09 March 2022 14:04 Write a comment
In Steven Spielberg's 1977 film "Close Encounters of the Third Kind," extraterrestrials communicate with humans through a catchy five-note sequence. In Spielberg's 1982 blockbuster "E.T.," a diminutive alien learns basic English from a children's TV show. More recently, in 2016's "Arrival," squid-like visitors use pictograms to make themselves understood to American scientists wielding whiteboards with words.
Finding moons' hidden oceans with induced magnetic fields
Wednesday, 09 March 2022 13:49 Write a comment
In the 21st century, planetary scientists have become increasingly aware that subsurface oceans consisting of liquid water exist within objects throughout the solar system. Because water is a universal requirement for life on Earth, these bodies—mostly moons—are enticing targets in the search for extraterrestrial life.
A primary way of deducing the existence of an unseen ocean is through an induced magnetic field. These fields originate from a unique application of Faraday's law of induction, which states that a time-varying magnetic field creates an electric current when applied to a circuit. Water that is salty enough to remain liquid in cold space environments is very conductive; at the same time, a moon's orbit through a planet's rotating magnetic field exposes the moon to a field strength that varies with time.
Canada answers Ukraine’s call for satellite radar imagery

Filling the GOCE data gap unearths South Pole’s geological past

It’s very difficult to know what lies beneath a blanket of kilometres-thick ice, so it is hardly surprising that scientists have long contested the shape and geology of the ancient supercontinent from which East Antarctica formed over a billion years ago. An ESA-funded study can now lay some of this conjecture to rest. Using sensors on aircraft to measure changes in the gravity and magnetic signatures of the different rocks under the ice, scientists have discovered a huge bay the size of the UK formed part of the edge of

There's a big rock stuck inside one of Perseverance's wheels
Wednesday, 09 March 2022 10:59 Write a comment
It looks like the Perseverance rover has an unwanted passenger, a rock stuck inside one of its wheels. The image of the stone was selected by public input as the "Image of the Week" for Week 54 (Feb. 20–26, 2022) of the Perseverance mission. Perseverance captured this image on February 25, 2022.
The rover's Front Left Hazard Avoidance Camera A captured the image. When the rover is driving, it makes periodic stops to let the Hazard Cameras survey the immediate surroundings. The Hazard Cameras help evaluate the hazards in front of and behind the rover, like large boulders, deep trenches, or dunes. The cameras create 3D views of the surroundings that help the rover make its own decisions without consulting with the rover team on Earth on every move.
The rock's been there for a few days, based on images from March 2. It's difficult to tell from the picture for sure, but it doesn't appear to be wedged in. Will it fall out during normal operations?
The rock doesn't appear to be causing any damage or hindering the rover's operations.
