‘Peekaboo’ Galaxy Emerges From Hiding, And It’s A Time Capsule of The Universe

Posted by in category: space

A galaxy that has taunted astronomers since they first detected a hint of its presence more than 20 years ago has finally emerged from hiding.

It’s called HIPASS J1131-31, or Peekaboo, and it is located just 22 million light-years away. And it was so hard to see because it’s teeny tiny and obscured by a bright star in the Milky Way that sits almost directly in front of it.

Through a collaborative effort that involved space-and ground-based telescopes, scientists have learned that the extremely small Peekaboo is also extremely young and close – offering a snapshot of galactic infancy.

Describing the genes associated with the sixth sense

Posted by in category: space

To perform coordinated movements, we rely on special sensory neurons in our muscles and joints. Without them, the brain wouldn’t know what the rest of our body was doing. A team led by Niccolò Zampieri has studied their molecular markers to better understand how they work and describes the results in Nature Communications.

Sight, hearing, smell, taste, touch: We’re all familiar with the five senses that allow us to experience our surroundings.

Equally important but much less well known is the sixth sense: “Its job is to collect information from the muscles and joints about our movements, our posture and our position in space, and then pass that on to our central nervous system,” says Dr. Niccolò Zampieri, head of the Development and Function of Neural Circuits Lab at the Max Delbrück Center in Berlin. “This sense, known as proprioception, is what allows the central nervous system to send the right signals through to muscles so that we can perform a specific movement.”

Graphene heads to the moon

Posted by in categories: health, space

The experiment is a collaboration between the University of Cambridge and Université Libre de Bruxelles – partner institutions of the European Commission’s Graphene Flagship – along with the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates, York University in Canada, and the European Space Agency (ESA).

Regolith is composed of extremely sharp, tiny and sticky grains and, since the Apollo missions, it has been one of the biggest challenges lunar missions have had to overcome. Regolith can cause mechanical and electrostatic damage to equipment and is therefore also hazardous for astronauts. It clogs spacesuits’ joints, obscures visors, erodes spacesuits and protective layers, and is a potential health hazard.

Cambridge researchers have produced special graphene composites that are meant to reduce regolith adhesion. The graphene samples will be monitored via an optical camera, which will record footage throughout the mission. Researchers from Université Libre de Bruxelles (ULB) will gather information during the mission and suggest adjustments to the path and orientation of the rover. Data and images obtained will be used to study the effects of the moon environment and the regolith abrasive stresses on the samples.

Unexpected Kilonova Discovery: Colossal Explosion Challenges Our Understanding of Gamma-Ray Bursts

Posted by in category: space

International Gemini Observatory uncovers surprising evidence of colliding neutron stars after probing aftermath of gamma-ray burst.

While investigating the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of telescopes in space and on Earth have uncovered the unexpected hallmarks of a kilonova. This is the colossal explosion triggered by colliding neutron stars. This discovery challenges the prevailing theory that long GRBs exclusively come from supernovae, the end-of-life explosions of massive stars.

Surprisingly, TRAPPIST-1’s violent flares could make life even more likely

A Ghostly Glow of Light Surrounds The Solar System, And Nobody Can Explain It

Posted by in category: space

A new analysis of Hubble data has clinched it: There’s too much light in the space around the Solar System.

Not much extra light, to be sure. Just a subtle, ghostly glow, a faint excess that can’t be accounted for in a census of all the light-emitting objects.

All the stars and galaxies surrounding the Solar System – and zodiacal light, aka dust on the Solar System’s plane – none of these can explain what astronomers are now calling “ghost light”.

Earth has been hit by an ‘unusual, intense blast of energy’ from a nearby galaxy

Posted by in categories: energy, space

And the galaxy from which the GRB came from is also strange. It is young and still forming stars – the opposite of the only other known nearby galaxy that has played host to such an event.

“This event looks unlike anything else we have seen before from a long gamma-ray burst,” said Jillian Rastinejad, from Northwestern University, who led the study. “Its gamma rays resemble those of bursts produced by the collapse of massive stars.

Given that all other confirmed neutron star mergers we have observed have been accompanied by bursts lasting less than two seconds, we had every reason to expect this 50-second GRB was created by the collapse of a massive star. This event represents an exciting paradigm shift for gamma-ray burst astronomy.

Is Information the Fifth State of Matter in the Universe?

“Information,” wrote Arizona State University astrophysicist Paul Davies in an email to The Daily Galaxy, “is a concept that is both abstract and mathematical. It lies at the foundation of both biology and physics.”
