Encrypted “Alien” Radio Signal Decrypted via Social Media
22nd June 2017 | Space, Tech

One of the more intriguing unsolved modern mysteries is the fast radio burst (FRB) phenomenon. Over the last several years, radio telescopes on Earth have been detecting more and more very brief, very powerful radio signals which originate from deep space. While astronomers have been able to locate the source of several of these signals, the exact mechanisms of their production remain a mystery.

General relativity passes test at Milky Way’s central black hole
22nd June 2017 | | Space

Einstein’s greatest theory has aced another test. Two stars are speeding around the big black hole at the Milky Way’s core in just the way his general theory of relativity predicted.

“It’s the first time that general relativity is really tested around a supermassive black hole,” says Aurélien Hees at the University of California, Los Angeles.

We Live in a Cosmic Void, Another Study Confirms
22nd June 2017 | | Space

Earth and its parent galaxy are living in a cosmic desert — a region of space largely devoid of other galaxies, stars and planets, according to a new study.

The findings confirm the results of a previous study based on observations taken in 2013.

The largest virtual universe ever simulated
21st June 2017 | Space, Tech

Researchers from the University of Zurich have simulated the formation of our entire universe with a large supercomputer. A gigantic catalogue of about 25 billion virtual galaxies has been generated from 2 trillion digital particles. This catalogue is being used to calibrate the experiments on board the Euclid satellite, that will be launched in 2020 with the objective of investigating the nature of dark matter and dark energy.

Light wormholes could wire space invisibly
19th June 2017 | | Space

A prescription for wormholes that transmit light invisibly between remote regions has been devised by a team of researchers. These ‘electromagnetic wormholes’ are the light-based equivalent of space-time wormholes, the staples of science fiction that permit time travel and create short cuts across intergalactic space. They could one day be used in three-dimensional (3D) video-display units wired up with invisible light-carrying cables.

Physicists review three experiments that hint at a phenomenon beyond the Standard Model of particle physics
19th June 2017 | Space

To anyone but a physicist, it sounds like something out of “Star Trek.” But lepton universality is a real thing.

It has to do with the Standard Model of particle physics, which describes and predicts the behavior of all known particles and forces, except gravity. Among them are charged leptons: electrons, muons and taus.

Einstein’s ‘Impossible’ Experiment Finally Performed
19th June 2017 | Space

The Hubble telescope just weighed a star using a technique the famed physicist described but said humanity would have “no hope” of using.

Orion Transformed: Familiar Constellation Will Shift Over Millennia
19th June 2017 | | Ancient, Space

Humans observing the sky as they walked out of Africa millennia ago would have seen different night skies than the ones people see today. And humans in the far future will see another, different celestial landscape.

The First Space-Based ‘Nation’ Wants to Store Data Off-Planet, Beyond the Law
17th June 2017 | Space

Self-proclaimed ‘space nation’ Asgardia will launch a satellite later this year to test the concept of long-term data storage in orbit around the Earth. This potentially opens the door to off-planet data and tax havens, according to filings obtained by Motherboard, and represents an important step towards the group’s proclaimed goal of starting a private nation in space.

Talking to E.T.? Why Math May Be the Best Language
17th June 2017 | | Space

Carl DeVito, an emeritus faculty in the mathematics department at the University of Arizona in Tucson, has proposed a language based on plausibly universal scientific concepts.

Comet Likely Didn’t Cause Bizarre ‘Wow!’ Signal (But Aliens Might Have)
17th June 2017 | | Space

An astronomer thinks he’s pinpointed the source of a mysterious radio signal from space: a passing comet that nobody knew about. But his colleagues said they’re still skeptical of the explanation, noting that comets don’t emit radio waves in the right way.

The mystery xenon in Earth’s atmosphere came from icy comets
17th June 2017 | | Space

The origin of the xenon in Earth’s atmosphere has been a mystery for decades. Now, using data from the Rosetta spacecraft’s tight orbits around a comet, researchers have determined that 22 per cent came from comets. This strengthens suspected connections between these celestial bodies and Earth’s evolution.

Earth Could Face A Grave Asteroid Threat This Autumn
17th June 2017 | Space

Aside from all the neato deep space exploration NASA conducts, one of the space agency’s responsibilities includes keeping track of all the potentially dangerous objects hurtling around our own neck of the space woods. NASA tracks over 15,000 so-called near-Earth objects (NEOs), many of which have been passing uncomfortably close to Earth lately.

Microbes might thrive after crash-landing on board a meteorite
17th June 2017 | | Space

Bacteria riding on an incoming meteorite may be able to survive the violent shockwave created when it crash-lands on a planet. Their cell walls have been seen to rapidly harden and relax after a sudden shock compression, enabling them to bounce back even after an extreme collision.

New research shows that astronauts traveling beyond the Earth’s geomagnetic sphere are at a risk for cancer that’s twice as high as previously thought. The study’s team points out that this research must inform all protective measures in space.

Window to a watery past on Mars
17th June 2017 | Space

This 70 km-wide crater and its surrounds offer a window into the watery past of the Red Planet.

The scene, captured by ESA’s Mars Express, is a composite of two images taken in March 2007 and February 2017.
