Making better measurements of the composition of galaxies

Posted by in category: space

A study using data from telescopes on Earth and in the sky resolves a problem plaguing astronomers working in the infrared, and could help make better observations of the composition of the universe with the James Webb Space Telescope and other instruments. The work is published April 20 in Nature Astronomy.

“We’re trying to measure the composition of gases inside galaxies,” said Yuguang Chen, a postdoctoral researcher working with Professor Tucker Jones in the Department of Physics and Astronomy at the University of California, Davis.

Most elements other than hydrogen, helium and lithium are produced inside stars, so the composition and distribution of heavier elements—especially the ratio of oxygen to hydrogen—can help astronomers understand how many and what kinds of stars are being formed in a distant object.

Strange radio signals detected from Earth-like planet could be a magnetic field necessary for life

Posted by in category: space

Earth’s magnetic field protects life on our blue planet — and astronomers just found evidence of a magnetic field on a rocky exoplanet 12 light-years away.

Look! Hubble Image Celebrates the Telescope’s 33rd Anniversary with a Cosmic “Laser Lightshow”

Posted by in category: space

Behold a stellar nursery, where starlight scatters through interstellar dust — and sometimes can’t pierce the space soot.


This gorgeous Hubble image is a celebration of the telescope’s 33rd space birthday.

Functional organization of social perception networks in the human brain

Posted by in category: space

Humans rapidly extract diverse and complex information from ongoing social interactions, but the perceptual and neural organization of the different aspects of social perception remains unresolved. We showed short movie clips with rich social content to 97 healthy participants while their haemodynamic brain activity was measured with fMRI. The clips were annotated moment-to-moment for a large set of social features and 45 of the features were evaluated reliably between annotators. Cluster analysis of the social features revealed that 13 dimensions were sufficient for describing the social perceptual space. Three different analysis methods were used to map the social perceptual processes in the human brain. Regression analysis mapped regional neural response profiles for different social dimensions. Multivariate pattern analysis then established the spatial specificity of the responses and intersubject correlation analysis connected social perceptual processing with neural synchronization. The results revealed a gradient in the processing of social information in the brain. Posterior temporal and occipital regions were broadly tuned to most social dimensions and the classifier revealed that these responses showed spatial specificity for social dimensions; in contrast Heschl gyri and parietal areas were also broadly associated with different social signals, yet the spatial patterns of responses did not differentiate social dimensions. Frontal and subcortical regions responded only to a limited number of social dimensions and the spatial response patterns did not differentiate social dimension. Altogether these results highlight the distributed nature of social processing in the brain.

A Quantum Leap Through Time: Famous Double-Slit Experiment Reimagined

Posted by in categories: physics, space

Physicists have recreated the double-slit experiment in time rather than space, using materials that change their optical properties in femtoseconds. This research could lead to ultrafast optical switches and advancements in time crystals and metamaterials.

Metamaterials are engineered materials that have properties not usually found in nature.

New exoplanet seen via direct imaging

Posted by in category: space

The discovery of HIP 99,770 b, a new exoplanet located 133 light years away, is reported in the journal Science. A team of astronomers used a new detection method that combines direct imaging with astrometry.

As of today, there are 5,363 confirmed exoplanets in 3,960 planetary systems. However, only a handful have been seen via direct imaging. Exoplanets are extremely faint compared with their parent stars, making it difficult to spot them in visible light.

Axiom announces new government human spaceflight program

Posted by in categories: government, space, sustainability

COLORADO SPRINGS — Axiom Space has introduced a new program to allow countries to create human spaceflight programs without needing to develop their own infrastructure or other capabilities.

The Axiom Space Access Program, announced April 17, offers countries a tiered approach to conducting research on the International Space Station or Axiom’s future commercial space station, as well as flying their own astronauts.

The program is effectively a “space program in a box,” said Tejpaul Bhatia, chief revenue officer at Axiom, in an interview during the 38th Space Symposium. “The real key is that turnkey access at affordable, sustainable and predictable rates.”

THE CHALLENGE First trailer EN

Posted by in categories: biotech/medical, space

THE CHALLENGE, FIRST FEATURE FILM SHOT IN SPACE: Thoracic surgeon Evgenia Belyaeva has one month to prepare for a flight to the International Space Station, where she must operate on a crew member. Will she be up for the challenge? Can she overcome her fears and insecurities? Will she be able to perform the complicated surgery in zero gravity, and give the cosmonaut a chance to return to Earth alive?

The Russians have long been at the forefront of scientific and technological innovation. With the historic launch of Yuri Gagarin into space in 1961, they made history by becoming the first country to send a human being into orbit. Decades later, they have once again made headlines by being the first in the world to develop a COVID-19 vaccine, a remarkable achievement in the face of a global pandemic. And now, they have again beaten everyone else by shooting the first-ever movie in space.
