New Technique Used to Spot Possible Super-Earth in Alpha Centauri's Habitable Zone
Astronomers using a new technique may have not only found a super-Earth at a neighbouring star, but they may also have directly imaged it. And it could be nice and cozy in the habitable zone around Alpha Centauri.

The Origin of Modern Humans Cannot Be Traced to Any One Single Point in Time or Space
Homo sapiens today look very different from our evolutionary origins, the microbes wriggling about in the primordial mud. But our emergence as a distinct species cannot, based on the current evidence, be conclusively traced to a single location at

In a Weird Twist, Scientists Discover Venus Flytraps Generate Little Magnetic Fields
The Venus flytrap (Dionaea muscipula) is already a fascinating enough plant, but scientists have discovered something else amazing about it: It generates measurable magnetic fields as its leaves snap shut.

7 Minutes to Land on Mars: NASA's Perseverance Rover Will Attempt Most Dangerous Landing Yet
All landings on Mars are difficult, but NASA's Perseverance rover is attempting to touch down in the most challenging terrain on Mars ever targeted.
The intense entry, descent, and landing phase, known as EDL, begins when the spacecraft reaches the top of the Martian atmosphere. Engineers have referred to the time it takes to land on Mars as the "seven minutes of terror."
The Perseverance rover is set to land on the surface of Mars on February 18, 2021.
Are you excited?

The Best Way to Find Aliens on Other Worlds May Be to Search For Signs of Their Smog
The Universe is a big place, so scientists are keen to narrow down their search for alien life – maybe by looking for radio signals, or hospitable climates, or huge megastructures. Now another sign of alien life is under consideration: atmospheri

NASA’s Ingenuity Mars Helicopter: Attempting the First Powered Flight on Mars
NASA's Ingenuity Mars Helicopter will make history's first attempt at powered flight on another planet. The agency's Mars 2020 Perseverance rover with Ingenuity attached to its belly, will land on Mars February 18.
As a technology demonstration, Ingenuity is testing a new capability for the first time: showing controlled flight is possible in the very thin Martian atmosphere. If successful, Ingenuity could lead to an aerial dimension to space exploration, aiding both robots and humans in the future.

Mystery Lifeforms Have Been Found in The Hostile Darkness Beneath Antarctica
It's pitch dark, and temperatures are subzero; yet, when scientists drilled through an Antarctic ice shelf far from light or warmth, they found a seafloor boulder that's home to several species we may have never seen before.

Two variants have merged into heavily mutated coronavirus
Two variants of the SARS-CoV-2 coronavirus that causes covid-19 have combined their genomes to form a heavily mutated hybrid version of the virus. The “recombination” event was discovered in a virus sample in California, provoking warnings that we may be poised to enter a new phase of the pandemic.
The hybrid virus is the result of recombination of the highly transmissible B.1.1.7 variant discovered in the UK and the B.1.429 variant that originated in California and which may be responsible for a recent wave of cases in Los Angeles because it carries a mutation making it resistant to some antibodies.

Mars 2020 Landing Timeline
Perseverance is the most sophisticated rover NASA has ever sent to the Red Planet and it will begin it's landing phase at 20:38 UTC tomorrow evening.
The intense entry, descent, and landing (EDL) phase begins when the spacecraft reaches the top of the Martian atmosphere, traveling at about 19,500 kph (12,100 mph).
EDL ends about seven minutes later, with the rover stationary on the Martian surface. Many engineers refer to the time it takes to land on Mars as the “seven minutes of terror.”

Atmospheric Entry
10 minutes before entering the Martian atmosphere – the Mars 2020 spacecraft will shed the cruise stage that helped fly Perseverance and Ingenuity to Mars.
The spacecraft will manipulate its descent into Mars’ atmosphere using a technique called guided entry to reduce the size of the targeted ellipse-shaped landing area on Mars while compensating for variations in the density of the Martian atmosphere and drag on the vehicle.
During guided entry, small thrusters on the back of the aeroshell will adjust the angle and direction of lift, enabling the spacecraft to control how far downrange it is flying.

New EDL Technologies
While all landings on Mars are difficult, Perseverance is landing in the most challenging terrain ever targeted. Jezero Crater is a 28-mile-wide (45-kilometer-wide) impact basin with an intriguing ancient river delta as well as steep cliffs, sand dunes, boulder fields, and smaller impact craters.
During EDL, Range Trigger will autonomously update the deployment time for the parachute based on navigation position.
It will calculate the spacecraft’s distance to the landing target and open the parachute at the ideal time for the spacecraft to hit its mark. The result: a smaller, more precise landing ellipse, or target landing area.
The landing ellipse for Perseverance is 10 times smaller in area than the Curiosity rover’s in 2012 and almost 300 times smaller than that of the first Mars rover, Sojourner, in 1997.
