A nearly 3,500-year-old brown bear that was nearly perfectly preserved in Siberian permafrost is now being dissected by Russian researchers.

The female bear has undergone a necropsy after it was discovered by reindeer herders on Bolshoy Lyakhovsky Island in the Arctic in 2020. 

It was found just east of the Bolshoy Etherican River and, therefore, has been named the Etherican brown bear.

The extreme temperatures in the area helped to preserve the bear’s soft tissue for 3,460 years, as well as the remains of its final meals.

The 5.09-foot tall and almost 172-pound bear had ingested birds and plants. 

The team cut through the bear’s hide – with the tissue and fat visible – and scientists examined its brain and internal organs. They used a vacuum to suck up the skull bone dust.

It remains unclear how the bear came to be on the island, which is divided from the mainland. Melting permafrost has been altering Siberia’s landscape.

“Genetic analysis has shown that the bear does not differ in mitochondrial DNA from the modern bear from the north-east of Russia – Yakutia and Chukotka,” Cheprasov told Reuters, noting the find is “absolutely unique.”

The Dragon capsule will start out attached to the Falcon 9 booster, which is fueled with liquid oxygen and rocket grade kerosene, and powered by nine SpaceX Merlin engines.

The northern lights were captured on video Sunday dancing over Alaska skies.

The green lights shimmered over Anchorage terrain and communities. 

The auroras made an appearance across the Northern Hemisphere through Monday morning, with reports as far south as Ohio. 

The waves of light are caused by the sun. While the sun sends energy and small particles, the Earth is protected by its magnetic field. Some outputs are stronger than others, including solar storms.

When the solar storm heads toward Earth, some of the energy and small particles can travel down the magnetic field lines at the north and south poles into Earth’s atmosphere. There, the particles interact with gases in the atmosphere, creating the light displays.

Oxygen gives off green and red light, and NASA says nitrogen glows blue and purple. 

The aurora is named for the Roman goddess of dawn. While the aurora borealis occurs in the north, the southern pole sees the aurora australis, or southern lights.

Over the weekend, two solar storms – coronal mass ejections – occurred.

A piece of the SS Savannah was likely found on a New York shoreline following Tropical Storm Ian last fall.

After becoming the first vessel to cross the Atlantic Ocean partly under steam power, the ship ran aground and broke apart more than 200 years ago.

The 13-foot, square piece of wreckage was located off Fire Island in October. 

It is now in the custody of the Fire Island Lighthouse Preservation Society, which is working with the National Park Service to identify it and put it on public display.

Park service officials reportedly said that while it may be difficult to identify the wreckage with full certainty, the Savannah is a top contender among the area’s known shipwrecks. 

“It was pretty thrilling to find it,” said Betsy DeMaria, a museum technician at the park service’s Fire Island National Seashore, told The Associated Press. “We definitely are going to have some subject matter experts take a look at it and help us get a better view of what we have here.”

Last week, the Florida Department of Health in Lee County issued a health alert after waters around Lynn Hall Memorial Park near Times Square on Fort Myers Beach were tested and found to have alert levels of red tide.

“An increased level of dead fish washing up with tides can be caused by Red Tide, which is a toxic algae bloom that periodically happens,” Fort Myers town spokesperson Jennifer Dexter shared in a statement.

According to the Florida Fish and Wildlife Commission (FWC), red tide occurs “when microscopic algae multiply to higher-than-normal concentrations.” Also known as harmful algal blooms (HABs) the red tide in Southwest Florida is K. brevis. This specific species produces brevetoxins, which is capable of killing fish, birds and other marine life. The FWC also said it can be harmful to humans and cause respiratory issues.

On Monday, Feb. 27, the Town of Fort Myers Beach announced that staff has, “been working on the beach daily to remove an increasing amount of dead fish that have started washing up daily.” The town is using equipment from Lee County and started working on clearing the beaches on Tuesday, Feb. 26.

“The Town’s Environmental Services Manager started working last week with the Florida Department of Environmental Protection (FDEP) to receive official approval in the form of a permit to use heavier equipment to remove the fish.” Dexter shared.

According to the Florida Fish and Wildlife Conservation Commission, dead fish and eels also been reported in Pinellas, Manatee, Sarasota, Charlotte, Lee, and Collier counties.

The National Park Service said Wednesday that peak bloom for the world-famous Washington, D.C., cherry trees around the Tidal Basin and the Washington Monument is predicted to fall between March 22 and 25. 

The trees, represented by 12 different varieties, were given as a gift from Japan in 1912. While the initial gift totaled 3,020 trees, there are now approximately 3,800 cherry trees within the park.

Peak bloom is defined as the time when 70% of the Yoshino cherry blossoms are open. 

This time varies annually depending on weather conditions.

However, the most likely time to reach peak bloom is between the last week of March and the first week of April. 

Previously, extraordinarily warm or cool temperatures have resulted in peak bloom as early as March or as late as April.

The European Space Agency said Friday that an investigation into the failure of a rocket carrying two Earth observation satellites last year indicated the cause was a faulty part procured from Ukraine.

The Vega C rocket ditched in the sea less than three minutes after liftoff from a spaceport in French Guiana in December. Arianespace, which provided the launch service, said at the time that decrease in pressure was observed in the rocket’s second stage, “leading to the premature end of the mission.”

“The cause of the failure was a gradual deterioration of the Zefiro 40’s nozzle,” the European Space Agency said.

The Zefiro 40 second stage, made by Italian space company Avio, suffered “an unexpected thermo-mechanical over-erosion” of a carbon component procured in Ukraine, it said.

Pierre-Yves Tissier of Arianespace said the conclusion was based on an examination of identical parts and still needed to be confirmed through further tests.

ESA added that during the inquiry “no weakness in the design of Zefiro 40 has been revealed.”

The launch was the third failure in the past eight launches of Vega and Vega C rockets, an embarrassment for the agency and its partners.

“We will overcome this very difficult moment,” Arianespace head Stephane Israel told reporters.

ESA chief Josef Aschbacher added that measures would now be implemented “to get out of this crisis stronger.”

The launch was meant to take two Earth observation satellites made by Airbus, Pleiades Neo 5 and 6, into orbit. The satellites would have been part of a constellation capable of taking images of any point on the globe with a resolution of 12 inches.

Israel acknowledged on Friday that an inscription in clay found in the country’s south bearing the name of Darius the Great, ruler of the ancient Persian Empire, was not authentic.

The shard of pottery in question was discovered by a passerby last December and caused a sensation as the first mention of sixth century B.C. empire builder to appear in Israel.

After the news broke earlier this week, an expert in ancient Aramaic inscriptions approached the Israel Antiquities Authority to explain that she herself had actually etched those words onto the ancient fragment.

EGYPTIANS DEMAND BRITISH MUSEUM RETURN ROSETTA STONE TO EGYPT

The unnamed expert, part of a foreign expedition last summer to the Tel Lachish archaeological site, told officials that she had scratched the words into pottery as a demonstration while explaining to students how artifacts were historically inscribed.

She said that she then left the altered piece at the site where a Canaanite city once stood, about 40 kilometers southwest of Jerusalem, the Antiquities Authority said.

Israel found that the inscription bearing the name of Darius the Great on a Persian pottery shard was inauthentic.

Authorities said they determined the misidentification of the artifact had come about “unintentionally and without malice” but described the expert’s decision to leave behind the newly inscribed shard as “careless.” The piece of pottery was examined in labs and found to be ancient, creating confusion.

Gideon Avni, the chief scientist of the Antiquities Authority, said it “takes full responsibility for the unfortunate event.”

“In terms of ethical and scientific practices, we see this as a very severe occurrence,” he said, noting that such cases remain extremely rare.

The authority said it will conduct a review of all procedures and policies at foreign expeditions nationwide. It was not immediately clear if any action would be taken against the unnamed expert behind the inscription.

International scientists have uncovered new clues about the supernova remnant called Tycho.

The findings shed light on how conditions in the shock waves caused by titantic stellar explosions – known as supernovae – accelerate particles to near the speed of light.

Astronomers used NASA’s Imaging X-ray Polarimetry Explorer to look at polarized X-rays from the Tycho supernova remnant. NASA said the star’s explosion was discovered 450 years ago.

For the first time, IXPE revealed the geometry to the magnetic fields close to the shock wave, which is still propagating from the initial explosion and forms a boundary around the ejected material.

ROCKET LAUNCH FAILURE LIKELY CAUSED BY FAULTY PART FROM UKRAINE

Using data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE), international researchers have uncovered new information about the Tycho supernova remnant, an exploded star in the constellation Cassiopeia, the light from which was first seen on Earth in 1572. The results offer new clues about how shock waves created by these titanic stellar explosions accelerate particles to nearly the speed of light, and reveal, for the first time, the geometry of the magnetic fields close to the supernova’s blast wave, which forms a boundary around the ejected material, as seen in this composite image. IXPE data (dark purple and white) have been combined with data from NASA’s Chandra X-ray Observatory (red and blue) and overlaid with the stars in the field of view as captured by the Digitized Sky Survey. (Credits: X-ray (IXPE: NASA/ASI/MSFC/INAF/R. Ferrazzoli, et al.), (Chandra: NASA/CXC/RIKEN & GSFC/T. Sato et al.) Optical: DSS Image processing: NASA/CXC/SAO/K. Arcand, L.Frattare & N.Wolk)

By measuring X-ray polarization, the authors of a study published in The Astrophysical journal can determine the average direction and ordering of the magnetic field of light ways that make up X-rays from a high-energy source like the remnant.

The polarized X-rays are produced in a process called synchrotron emission, and the polarization direction from the X-rays can be mapped back to the direction of the magnetic fields at the location where the X-rays were generated.

Building on groundwork laid by NASA’s Chandra X-ray Observatory, IXPE allows scientists to better understand the process in which cosmic rays – highly energetic particles – are accelerated by supernova remnants. It helped map the shape of Tycho’s magnetic field, measuring it on scales smaller than one parsec.

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this “new star” was far beyond the moon, and that it was possible for the universe beyond the sun and planets to change. (Image Credit: X-ray: NASA/CXC/RIKEN & GSFC/T. Sato et al; Optical: DSS)

It’s the closest researchers have ever come to observing the source of the cosmic rays emitted by one of these distant phenomena.

The supernova’s namesake, Danish astronomer Tycho Brahe noticed the “star” in the constellation Cassiopeia in 1572.

The Tycho supernova is classified as a Type Ia, which occurs when a white dwarf star in a binary system shreds its companion star, capturing some of its mass and leading to a violent explosion.

The James Webb Space Telescope has captured an image that may make viewers double take. 

The shot features a special galaxy cluster – known as RX J2129 – and three different images of the same supernova-hosting galaxy.

RX J2129 is located approximately 3.2 billion light-years from Earth in the constellation Aquarius. 

The tripled galaxy is shown this way due to gravitational lensing. 

SCIENTISTS REVEAL NEW CLUES ABOUT HISTORIC TYCHO SUPERNOVA

This observation from the NASA/ESA/CSA James Webb Space Telescope features the massive galaxy cluster RX J2129. Due to Gravitational lensing, this observation contains three different images of the same supernova-hosting galaxy, which you can see in closer detail here. Gravitational lensing occurs when a massive celestial body causes a sufficient curvature of spacetime to bend the path of light travelling past or through it, almost like a vast lens. In this case, the lens is the galaxy cluster RX J2129, located around 3.2 billion light-years from Earth in the constellation Aquarius. Gravitational lensing can cause background objects to appear strangely distorted, as can be seen by the concentric arcs of light in the upper right of this image. (ESA/Webb, NASA & CSA, P. Kelly )

Gravitational lensing occurs when a massive celestial body causes a sufficient curvature of spacetime to bend the path of light traveling past or through it – like a vast lens.

The mass and gravity of the galaxy cluster is so great that time and space around it is warped, magnifying, multiplying and distorting galaxies behind it.

The supernova in the triple-lensed background galaxy was discovered by astronomers using the Hubble Space Telescope.

It contains a Type Ia supernova. Supernovae are explosions that take place during the final stages of the death of a supermassive star. A Type Ia supernova occurs roughly once every 500 years in the Milky Way and NASA says evidence shows it originates from some binary star systems that contain at least one white dwarf – the small, hot core remnant of a sun-like star.

This observation from the NASA/ESA/CSA James Webb Space Telescope contains three different images of the same supernova-hosting galaxy, all of which were created by a colossal gravitational lens. (ESA/Webb, NASA & CSA, P. Kelly)

The supernovae produce a fairly consistent luminosity, which allows astronomers to calculate astronomical distances. Scientists are able to understand how strongly the galaxy cluster is magnifying background objects and how massive it is. 

“As well as distorting the images of background objects, gravitational lenses can cause distant objects to appear much brighter than they would otherwise,” the European Space Agency said in a post. “If the gravitational lens magnifies something with a known brightness, such as a Type Ia supernova, then astronomers can use this to measure the ‘prescription’ of the gravitational lens.”

Furthermore, the spectroscopy of the supernova was obtained, allowing for the comparison of the supernova to Type Ia supernovae in the nearby universe. 

The agency said that this is an important way to verify that methods of measuring vast distances works as expected.
