Two 'alien' minerals never before seen on Earth are discovered in a 14-ton meteorite that crashed in Somalia two years ago

At least two new minerals never seen on Earth have been identified within a 14-ton meteorite found in Somalia two years ago.

The minerals were found in a single two-ounce slice of the space rock, which was sent to the University of Alberta, believed to have discovered a potential third new mineral.

The two newly discovered minerals have been named elaliite and elkinstantonite, but no other details have been released.

The meteorite, dubbed 'El Ali,' is classified as an 'Iron, IAB complex,' which is one of over 350 in that particular category - but it is the ninth largest meteorite ever found.

The meteorite was named in honor of the town where it was found, which is the name also given to the first mineral.

The second was named after Lindy Elkins-Tanton, director manager of Arizona State University's Interplanetary Initiative and principal investigator of NASA's upcoming Psyche mission.

Elkins-Tanton plans to send a probe to probe the mineral-rich asteroid for evidence of how our solar system's planets formed.

Chris Herd, a professor in the Department of Earth & Atmospheric Sciences and curator of the University of Alberta's Meteorite Collection, said in a statement: 'Whenever you find a new mineral, it means that the actual geological conditions, the chemistry of the rock, was different than what's been found before.

'That's what makes this exciting: In this particular meteorite, you have two officially described minerals that are new to science.'

Herd is also optimistic that more new minerals could be uncovered if researchers take more samples from the meteorite.

Paddington Bear on Mars? NASA images from the red planet capture the internet’s imagination

Paddington Bear on Mars? NASA images from the red planet capture the internet’s imagination​

Is it a bear? A wolf? A “doge?” The internet has mixed opinions on an image released by NASA showing what looks like a bear’s face on Mars.

NASA’s Mars Reconnaissance Orbiter, which has been orbiting the Red Planet and sending back high-resolution photos for about 17 years, captured the image on Dec. 12. The orbiting camera is part of the High Resolution Imaging Science Experiment, known as HiRISE, which is managed by the University of Arizona Lunar and Planetary Laboratory in Tucson, Arizona.

When HiRISE shared the bear photo on Twitter, the internet had its own ideas about what the figure resembles. Some said it looks more like “Doge,” the famed internet meme-turned cryptocurrency. Others posed that it’s an owl’s face. Some speculated that it was popular film and children’s book character Paddington Bear

What it really is, researchers say, is a hill with a V-shaped collapse structure (the nose), two craters for the eyes and a “circular fracture pattern” that makes up the head.

“The circular fracture pattern might be due to the settling of a deposit over a buried impact crater,” HiRISE researchers say.

“Maybe just grin and bear it,” they joked.

According to HiRISE, the Mars Reconnaissance Orbiter camera “operates in visible wavelengths, the same as human eyes, but with a telescopic lens that produces images at resolutions never before seen in planetary exploration missions.”

“These high-resolution images enable scientists to distinguish 1-meter-size (about 3-foot-size) objects on Mars and to study the morphology (surface structure) in a much more comprehensive manner than ever before,” according to the HiRISE website.

A "CHAIN REACTION" EXPLOSION ON THE SUN - MAJOR BLACKOUTS AHEAD? A magnetic filament connected to sunspot AR3229 erupted on Feb. 24th, producing a chain reaction of events that could lead to a geomagnetic storm on Earth. The action began at 1949 UTC when the filament rose up and sliced through the sun's atmosphere:



The violent liftoff destabilized sunspot AR3229, sparking a long duration M3-class solar flare (2030 UTC). Radiation from the flare, in turn, ionized the top of Earth's atmosphere, blacking out shortwave radio transmissions around the Pacific Ocean:



Next, a CME emerged from the blast site. Type II solar radio emissions from the leading edge of the CME suggest a departure speed of 1200 km/s (2.7 million mph). The flank of the fast-moving cloud could reach Earth on Feb. 27th. NOAA analysts are modeling the CME now, so stay tuned for a refined forecast. Coronagraph images from SOHO show a lopsided halo with an Earth-directed component:



Shock waves inside the CME accelerated protons to nearly light speed, and they have already reached Earth. Our planet's magnetic field is funneling the particles toward the poles where a second type of radio blackout is underway--a polar cap absorption (PCA) event. Airplanes flying over these regions may find that their shortwave radios won't work due to the ionizing effect of infalling protons:

Don't make plans for Valentine's Day 2046! NASA warns asteroid the size of Leaning Tower of Pisa is on a collision course with Earth - and LA and NYC are possible impact zones

NASA warns city-destroying asteroid could smash into Earth on Valentine's Day 2046
An asteroid around the same size of the Leaning Tower of Pisa was discovered by NASA last month. The collision of the 165-foot 2023 DW with our planet would be comparable to the Tunguska 12-megaton event that slammed into Siberia 114 years ago, which was similar to a nuclear explosion. 2023 DW has a chance of impacting Earth on February 14, 2046 at 4:44pm ET. A map showing potential impact zones lists Los Angeles and Washington DC as possible sites, but NASA said it is too soon to confirm.

REVEALED: The six asteroids that are on course to crash into Earth - including a space rock with a one in TEN chance of impact

Six asteroids on course to hit Earth - one has 10% chance

Space experts this week warned of an Olympic swimming pool-sized space rock that might hit Earth on Valentine's Day 2046 - but how many more are out there? The good news is that it's not time to head to the Doomsday bunkers yet - the Valentine's Day asteroid (2023 DW) was rapidly given lower odds of hitting Earth. But there are several asteroids out there with the potential to hit Earth in the coming centuries - although space agencies around the world are keeping a close eye on these.

NASA and the Canadian Space Agency (CSA) announced the four astronauts who will venture around the Moon on Artemis II, the first crewed mission on NASA’s path to establishing a long-term presence at the Moon for science and exploration through Artemis. The agencies revealed the crew members Monday during an event at Ellington Field near NASA’s Johnson Space Center in Houston.


“The Artemis II crew represents thousands of people working tirelessly to bring us to the stars. This is their crew, this is our crew, this is humanity's crew,” said NASA Administrator Bill Nelson. “NASA astronauts Reid Wiseman, Victor Glover, and Christina Hammock Koch, and CSA astronaut Jeremy Hansen, each has their own story, but, together, they represent our creed: E pluribus unum – out of many, one. Together, we are ushering in a new era of exploration for a new generation of star sailors and dreamers – the Artemis Generation.”

The crew assignments are as follows: Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist 1 Christina Hammock Koch, and Mission Specialist 2 Jeremy Hansen. They will work as a team to execute an ambitious set of demonstrations during the flight test.

The approximately 10-day Artemis II flight test will launch on the agency’s powerful Space Launch System rocket, prove the Orion spacecraft’s life-support systems, and validate the capabilities and techniques needed for humans to live and work in deep space.

“We are going back to the Moon and Canada is at the center of this exciting journey,” said the Honorable François-Philippe Champagne, the minister responsible for the Canadian Space Agency. “Thanks to our longstanding collaboration with NASA, a Canadian astronaut will fly on this historic mission. On behalf of all Canadians, I want to congratulate Jeremy for being at the forefront of one of the most ambitious human endeavors ever undertaken. Canada’s participation in the Artemis program is not only a defining chapter of our history in space, but also a testament to the friendship and close partnership between our two nations.”

The flight, set to build upon the successful uncrewed Artemis I mission completed in December, will set the stage for the first woman and first person of color on the Moon through the Artemis program, paving the way for future for long-term human exploration missions to the Moon, and eventually Mars. This is the agency’s Moon to Mars exploration approach.

“For the first time in more than 50 years, these individuals – the Artemis II crew – will be the first humans to fly to the vicinity of the Moon. Among the crew are the first woman, first person of color, and first Canadian on a lunar mission, and all four astronauts will represent the best of humanity as they explore for the benefit of all,” said Director Vanessa Wyche, NASA Johnson. “This mission paves the way for the expansion of human deep space exploration and presents new opportunities for scientific discoveries, commercial, industry and academic partnerships and the Artemis Generation.”

Meet Artemis II Astronauts
This will be Wiseman’s second trip into space, serving previously as a flight engineer aboard the International Station for Expedition 41 from May through November 2014. Wiseman has logged more than 165 days in space, including almost 13 hours as lead spacewalker during two trips outside the orbital complex. Prior to his assignment, Wiseman served as chief of the Astronaut Office from December 2020 until November 2022.

The mission will be Glover’s second spaceflight, serving previously as pilot on NASA’s SpaceX Crew-1, which landed May 2, 2021, after 168 days in space. As a flight engineer aboard the space station for Expedition 64, he contributed to scientific investigations, technology demonstrations, and participated in four spacewalks.
Koch also will be making her second flight into space on the Artemis II mission. She served as flight engineer aboard the space station for Expedition 59, 60, and 61. Koch set a record for the longest single spaceflight by a woman with a total of 328 days in space and participated in the first all-female spacewalks.

Representing Canada, Hansen is making his first flight to space. A colonel in the Canadian Armed Forces and former fighter pilot, Hansen holds a Bachelor of Science in space science from Royal Military College of Canada in Kingston, Ontario, and a Master of Science in physics from the same institution in 2000, with a research focus on Wide Field of View Satellite Tracking. He was one of two recruits selected by CSA in May 2009 through the third Canadian Astronaut Recruitment Campaign and has served as Capcom in NASA's Mission Control Center at Johnson and, in 2017, became the first Canadian to be entrusted with leading a NASA astronaut class, leading the training of astronaut candidates from the United States and Canada.

“I could not be prouder that these brave four will kickstart our journeys to the Moon and beyond,” said Director of Flight Operations Norm Knight, NASA Johnson. “They represent exactly what an astronaut corps should be: a mix of highly capable and accomplished individuals with the skills and determination to take on any trial as a team. The Artemis II mission will be challenging, and we’ll test our limits as we prepare to put future astronauts on the Moon. With Reid, Victor, Christina, and Jeremy at the controls, I have no doubt we’re ready to face every challenge that comes our way.”

Through Artemis missions, NASA will use innovative technologies to explore more of the lunar surface than ever before. We will collaborate with commercial and international partners and establish the first long-term presence on the Moon. Then, we will use what we learn on and around the Moon to take the next giant leap: sending the first astronauts to Mars.
