First observations from Inouye telescope bring previously hazy star into sharp focus.
The striking images reveal a surprising level of structure hidden within the churning plasma exterior, bringing a previously hazy impression of the sun’s patchwork surface sharply into focus for the first time.

Slideshow | Gravity, Light, Spacetime, and Universe | The Secrets of Our Universe as explained by The Theories of Relativity

Gravity is one of the four fundamental forces of nature. It is an immediate fact of
everyday experience, yet it presents us with some of the deepest theoretical and
experimental challenges in contemporary physics. Gravity is the weakest of the four
fundamental forces, but, because it is a universal attraction between all forms of
energy, it governs the structure of matter on the largest scales of space and time,
including the structure of the universe itself

Objects raise hopes of scientists managing to track ‘blobs’ being swallowed by black hole
A number of bizarre shape-shifting objects have been discovered close to the supermassive black hole at the centre of the Milky Way.
The blobs are thought to be giant stars that spend part of their orbits so close to the black hole that they get stretched out like bubble gum before returning to a compact, roughly spherical form.

From Sagan to Tesla, scientists have long puzzled over how to talk to extraterrestrial intelligence.
For the past 200 years, the problem of interstellar communication with an extraterrestrial intelligence has vexed some of the world’s greatest scientists and mathematicians. Carl Friedrich Gauss, the mathematician and inventor of the heliotrope, suggested using a large array of mirrors; Guglielmo Marconi and Nikola Tesla, pioneers of wireless communication, found a solution in radio waves; and John McCarthy and Marvin Minsky, the progenitors of artificial intelligence, wanted to send computers into space as our extraterrestrial envoys.

The detection of gravitational waves scooped the 2017 Nobel physics prize. But in a Perimeter Institute lecture Erik Verlinde proposes a rather different theory of gravity

Scientists say Milky Way’s Sagittarius A* has been more active in recent months. Unseeable and inescapable, black holes already rank among the more sinister phenomena out in the cosmos. So it may come as disconcerting news that the supermassive black hole at the centre of the Milky Way appears to be growing hungrier.

Inside Swamp Works, the NASA Lab Learning to Mine the Moon

Swamp Works is one of the few places in the world with an enormous test bed that mimics the conditions on the lunar surface. Inspired by Lockheed Martin’s Skunk Works, the lab responsible for several major aviation breakthroughs, Swamp Works was designed to bring the same agile spirit to NASA. And it’s where Schuler and about a dozen other researchers are prototyping robots to explore and mine the moon. In particular, they’re testing the Regolith Advanced Surface Systems Operations Robot, or Rassor, a four-wheeled contraption about the size of a motorcycle but only a fraction of the weight.
