Pulsars Confirm One of Einstein’s Best Ideas, That Freefall Really Feels Like You’re Experiencing a Lack of Gravity17 Jun 2020, 09:32 UTC General Relativity predicts that gravity and inertia are often indistinguishable. This has now been proven under the strongest conditions to date by precisely tracking the motion of a pulsar.
New Estimate Calculates There Could be 30 Intelligent Civilizations Communicating Across the Milky Way16 Jun 2020, 18:38 UTC Over the years, scientific estimates of potential intelligent life in our galaxy have ranged widely. Some estimates say just one (only us Earthlings) to just a handful, to possibly thousands or even millions. A new study attempts to quantify the number of other worlds we could potentially talk to by estimating the number of intelligent civilizations within the Milky Way that are actively communicating.
Bad Astronomy 16 Jun 2020, 13:00 UTC When you look up at the night sky, you can see thousands of stars. The fact that they're there at all implies they had a beginning, and we know stars can exist for billions of years. We see them die, and we see them being born. It's not a huge leap of logic to presume that, given the finite age of the Universe, there must have been a time when the very first stars were born.
NASASpaceFlight.com 16 Jun 2020, 10:36 UTC Two intrepid spacecraft are dancing with the Sun and making great progress toward the goal of learning more about our star. After NASA announced that Parker Solar Probe (PSP) had sent the “Status A” beacon after its fifth close flyby of the Sun, the European Space Agency (ESA) has announced that its Solar Orbiter has completed its first Perihelion.
Starts With a Bang! 15 Jun 2020, 14:01 UTC One of astronomy’s biggest surprises came in 2007, when a mysterious green object was found.
SciTech Daily 15 Jun 2020, 09:10 UTC A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that describes the fundamental nature of the Universe.
Universe Today 12 Jun 2020, 18:52 UTC Once the stuff of science fiction, the possibility that humans could establish a permanent settlement on Mars now appears to be a genuine possibility. While doing so represents a major challenge and there are many hurdles that still need to be overcome, the challenge itself is inspiring some truly creative solutions. But what is especially interesting is how these same solutions can also address problems here on Earth.
Starts With a Bang! 12 Jun 2020, 14:01 UTC It happened 13.8 billion years ago, so why hasn’t the radiation all passed over us by now?
