The James Webb Space Telescope’s First Year of Extraordinary Science Has Been Revealed

The James Webb Space Telescope’s First Year of Extraordinary Science Has Been Revealed

Years behind schedule and billions of dollars over budget, the James Webb Space Telescope (JWST) often finds itself the butt of jokes. From to more , the flagship project of NASA, the European Space Agency (ESA) and the Canadian Space Agency is an easy target. Yet many would argue that those delays and budget concerns are simply indicative of the telescope’s unprecedented scope and soaring ambitions. When it hopefully launches on October 31, it will be, by far, the largest and most sophisticated observatory ever sent into space. JWST will be poised to revolutionize our understanding of the...

The First 100 Days on Mars: How NASA’s Perseverance Rover Will Begin Its Mission

The First 100 Days on Mars: How NASA’s Perseverance Rover Will Begin Its Mission

On a space mission, timing is everything. An intricate choreography of commands and actions is required to make any such mission a success, and none more so than an escapade on the surface of another world. Now, on February 18, NASA is set for another delicate dance of interplanetary chronology when its Perseverance rover touches down on Mars—the successor to its aesthetically identical sibling, Curiosity, which landed in 2012. This time around, the mission is conducting a , alongside other exciting experiments.The 1,025-kilogram rover is powered by a radioisotope thermoelectric generator,...

Don’t Tell Einstein, but Black Holes Might Have ‘Hair’

Don’t Tell Einstein, but Black Holes Might Have ‘Hair’

nothing on black holes. Twins may grow from the same genetic blueprints, but they can differ in a thousand ways—from temperament to hairstyle. Black holes, according to Albert Einstein’s theory of gravity, can have just three characteristics—mass, spin and charge. If those values are the same for any two black holes, it is impossible to discern one twin from the other. Black holes, they say, have no hair. “In classical general relativity, they would be exactly identical,” said Paul Chesler, a theoretical physicist at Harvard University. “You can’t tell the difference.” reprinted with...

Alien Hunters Discover Mysterious Signal from Proxima Centauri

Alien Hunters Discover Mysterious Signal from Proxima Centauri

It’s never aliens, until it is. Today, news leaked in the British newspaper of a mysterious signal coming from the closest star to our own, Proxima Centauri, a star too dim to see from Earth with the naked eye that is nevertheless a cosmic stone’s throw away at just 4.2 light-years. Found this autumn in archival data gathered last year, the signal appears to emanate from the direction of our neighboring star and cannot yet be dismissed as Earth-based interference, raising the very faint prospect that it is a transmission from some form of advanced extraterrestrial intelligence (ETI)—a...

Asteroid Dust from Hayabusa2 Could Solve a Mystery of Planet Creation

Asteroid Dust from Hayabusa2 Could Solve a Mystery of Planet Creation

The toaster-sized capsule hit our atmosphere at 12 kilometers per second, enduring temperatures of 3,000 degrees Celsius during its fiery descent before deploying a parachute to slow its velocity. It continued to fall until it finally . Within hours, awaiting teams of scientists located the capsule’s landing site with radar and rushed via helicopter to retrieve it. On board were pieces of an asteroid, the biggest such haul in history, captured millions of kilometers from Earth and returned safely to our planet.This event, the climax of the Japanese space agency JAXA’s to the asteroid Ryugu,...

Quantum Time Twist Offers a Way to Create Schrödinger’s Clock

Quantum Time Twist Offers a Way to Create Schrödinger’s Clock

Albert Einstein’s twin paradox is one of the most famous in physics. It postulates that if you send one of two twins on a return trip to a star at near light speed, they will be younger than their identical sibling when they return home. The age difference is a consequence of something called time dilation, which is described by Einstein’s special theory of relativity: the faster you travel, the slower time appears to pass.But what if we introduce quantum theory into the problem? Physicists Alexander Smith of Saint Anselm College and Dartmouth College and Mehdi Ahmadi of Santa Clara...
