Astronomers discover misshapen galaxy is a cosmic predator that bears ‘scars’ from its last meal (photo)

NeRD

An unusual elliptical galaxy with a history of absorbing smaller galaxies appears to be approaching its next target. New images from the Very Large Telescope (VLT) at the European Southern Observatory’s (ESO) Paranal Observatory suggest that the galaxy, known as NGC 3640, may soon merge with a smaller galactic companion. Located 88 million light-years from Earth, NGC 3640 belongs to a group of galaxies that range in shape and size, including its own unusual oval or egg shape. The VLT images revealed that NGC 3640 has eaten other galaxies over…

Astronomers discover ‘Quipu,’ the single largest structure in the known universe

NeRD

Astronomers have discovered what may be the largest-scale structure in the known universe — a group of galaxy clusters and clusters of galaxy clusters that spans roughly 1.3 billion light-years across and contains a mind-boggling 200 quadrillion solar masses. The newfound structure is dubbed Quipu after an Incan system of counting and storing numbers using knots on cords. Like a Quipu cord, the structure is complex, made up of one long filament and multiple side filaments. It spans roughly 1.3 billion light-years (more than 13,000 times the length of the…

Einstein wins again! Quarks obey relativity laws, Large Hadron Collider finds

NeRD

Is there a time of day or night at which nature’s heaviest elementary particle stops obeying Einstein’s rules? The answer to that question, as bizarre as it seems, could tell scientists something very important about the laws of physics governing the cosmos. In a first-of-its-kind experiment conducted at the world’s most powerful particle accelerator, the Large Hadron Collider (LHC), scientists have attempted to discover if the universe’s heaviest elementary particle — a particle not composed of other smaller particles — always obeys Einstein’s 1905 theory of special relativity. More specifically,…

Some baby stars in ancient stellar nurseries were born in ‘fluffy’ cosmic blankets

NeRD

When it comes to baby blankets, the fluffier, the better — and astronomers have discovered that some infant stars in the early universe also preferred “fluffy” pre-natal cocoons. Stars are born in “stellar nurseries,” or regions of galaxies with an abundance of gas and dust that can become overly dense and collapse to form infant stars, or “protostars.” More accurately referred to as “molecular clouds,” these gaseous conglomerations can stretch for hundreds of light-years, thus forming thousands of stars. Scientists have learned a great deal about star formation in the…

Black holes snacking on small stars create particle accelerators that bombard Earth with cosmic rays

NeRD

Using 16 years of data from NASA’s gamma-ray detecting Fermi spacecraft, astronomers have discovered that “microquasars,” systems in which a black hole is slowly devouring a star, may be small, but they pack one heck of a punch. Despite their diminutive nature, this research suggests even microquasars snacking on small stars can have an impressive cosmic influence, becoming powerful natural particle accelerators. This means black holes indulging in stellar meals of all sizes could be responsible for a higher-than-suspected amount of high-energy charged particles called “cosmic rays,” which are constantly…

Japan’s Resilience moon lander aces lunar flyby ahead of historic touchdown try (photo)

NeRD

The private Resilience lunar lander just got its first up-close look at the moon. Resilience, which was built by Japanese company ispace, aced a flyby of the moon on Friday evening (Feb. 14), coming within a mere 5,220 miles (8,400 kilometers) of Earth’s nearest neighbor. The lander memorialized the milestone with a photo, snapping a nice shot of the battered lunar surface from a distance of 8,972 miles (14,439 km). The close encounter was “a historic first of its type for a Japanese private, commercial lunar lander,” according to ispace.…

‘City-killer’ asteroid 2024 YR4 could hit the moon instead of us, scientists say

NeRD

An asteroid that’s big enough to wipe out a city has a 1-in-43 chance of hitting our planet in the year 2032. But according to new calculations, there’s an even smaller chance that it might crash into the moon instead. On Feb. 7, NASA scientists increased the likelihood of asteroid 2024 YR4 colliding with Earth on Dec. 22, 2032, nearly doubling the odds from 1.2% to 2.3%. The potentially hazardous asteroid measures an estimated 180 feet (55 meters) across — about as wide as Walt Disney World’s Cinderella Castle is…

Continent-size blobs in Earth’s mantle are a billion years old, ancient crystals reveal

NeRD

Continent-size islands deep inside Earth’s mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and older than nearby areas of the mantle. The findings, published Jan. 22 in the journal Nature, shed light on Earth’s deep interior and could help explain how the mantle moves over time. Scientists have known about these LLSVPs for a few decades. The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the…

What the asteroid with a 1-in-48 chance of hitting Earth in 2032 looks like (images)

NeRD

It might not look like much in this image, but this is the asteroid that has made a major news impact in 2025. That’s because this space rock, designated asteroid 2024 YR4, has a 1-in-48 chance of impacting Earth in 2032. For obvious reasons, astronomers are desperate to learn as much as they can about 2024 YR4, estimated to be as large as 177 feet wide (54 meters wide). That’s around as wide as Cinderella’s Castle in Walt Disney World Florida is tall. The image featured here was captured on…
