Richard Holme, Professor of Geomagnetism at the University of Liverpool, said: “There has been speculation that we are about to experience a magnetic polar reversal or excursion. However, by studying the two most recent excursion events, we show that neither bear resemblance to current changes in the geomagnetic field and therefore it is probably unlikely that such an event is about to happen. Our research suggests instead that the current weakened field will recover without such an extreme event, and therefore is unlikely to reverse.” #EarthMagneticField
Mars solar conjunction, a period when Mars is on the opposite side of the Sun from Earth. During this time, the Sun can interrupt radio transmissions to spacecraft on and around the Red Planet. #solarconjunction
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. #exoplanets
Astronomers have discovered a stunning set of 39 massive galaxies
In the hunt for life on other worlds, astronomers scour over planets that are light-years away. They need ways to identify life from afar—but what counts as good evidence? #nasa
One of the fundamental questions humanity has always asked is how big is our Universe? For much of human history, people believed that Planet Earth was the very center of the entire universe. And Earth is pretty big. But compared the rest of the universe, we are infinitesimally small. Check it out in this PBS Space Time video. #astronomy #universe
New research suggests that regions of the Martian surface could be made habitable with a material — silica aerogel — that mimics Earth’s atmospheric greenhouse effect. Through modeling and experiments, the researchers show that a 2- to a 3-centimeter-thick shield of silica aerogel could transmit enough visible light for photosynthesis, block hazardous ultraviolet radiation, and raise temperatures underneath permanently above the melting point of water, all without the need for any internal heat source. #livingonmars
“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much-unexpected mass we detected,” said lead author Peter B. James, Ph.D.
The crucial elements for life on Earth, often called the building blocks of life, can be abbreviated as CHNOPS: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. For the first time, astronomers have cataloged the abundance of these elements in a huge sample of stars.
Given the signals’ energy, repeating nature and location, speculation has already begun on whether an advanced alien civilization is trying to contact us. The scientists haven’t ruled out the possibility that the signals originated from extra-terrestrial intelligence, however, they say it is more likely to be solar flares from a young neutron star.
NGC 2903 is a galaxy located about 30 million light-years away in the constellation of Leo (the Lion) and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disk galaxies.
Everything in the entire universe, everything that you and I perceive to be solid matter, is actually not matter at all. All the space around us is pure energy which we will call vacuum energy. Not only that, but this vacuum energy is infinitely dense.

Since the #moon is tidally locked to the Earth, for millennia we could only guess what mysteries lay on its “dark side.” Then in 1959 the Luna 3 spacecraft sent back a photo that prompted more questions than it answered.
