Are Human Beings Created By Aliens
Out of thousands of possible ways to assume how life on earth began, one of the possibilities remains that the life was created by an advanced alien civilization. As far as we have understood till now, the Universe was created about 13.7 billion years ago. Billions of stars and planets must have existed, way before the creation of the earth. Our earth was formed just 4.5 billion years ago.

There Could Be a Beautiful Reason Why Constellations Are The Same in Many Cultures
Human cultures can see the world through very different lenses, but the way we sort stars in the night sky is surprisingly universal.

New images of M87’s black hole reveal magnetized ring around it
In the nearly galaxy M87, more than 50 million light years from Earth, a supermassive black hole feeds on vast clouds of gas and dust. Jets, more than 5,000 light years long, erupt from this enigmatic body six billion times more massive than the Sun. In 2019, the first detailed images ever recorded of the region around a black hole were released, showing a bright ring-like structure surrounding a dark void.

Astronomers find the 'safest place' to live in the Milky Way
Astronomers have searched the entire Milky Way to identify the safest places to live. It turns out, we're in a pretty good spot. But if the past year has made you feel ready to relocate to another planet, you might want to look toward the center of the galaxy, according to the new research.

Interstellar object 'Oumuamua is a pancake-shaped chunk of a Pluto-like planet
The first known visitor from interstellar space, 'Oumuamua, was likely a pancake-shaped chip off a Pluto-like world, researchers say. These findings may shed light on the stuff a new class of planet, an exo-Pluto, is made of, scientists added.

Scientists Find New Patterns In Mysterious Radio Pulses From Distant Galaxies
The strange signals known as “fast radio bursts” (FRBs) have long mystified the astronomy community. The sudden, strong radio pulses, often emanating from distant galaxies, appear at regularly timed intervals, from every few of milliseconds to weeks — and we still aren’t entirely sure what they are or why they exist.

Rare supernova relic found at the core of our Milky Way
Data from NASA's Chandra X-ray Observatory suggests a supernova remnant known as Sagittarius A East (or Sgr A East) is the first known example of an unusual type of white dwarf stellar explosion called a Type Iax supernova in our own Milky Way galaxy.

What geologists see when they look at Perseverance's landing site
Geologists love fieldwork. They love getting their specialized hammers and chisels into seams in the rock, exposing unweathered surfaces and teasing out the rock's secrets. Mars would be the ultimate field trip for many of them, but sadly, that's not possible.

Claim for giant 'Planet Nine' at Solar System's edge takes a hit
For planetary scientists, it was the boldest claim in a generation: an unseen extra planet, as much as 10 times the mass of Earth, lurking on the Solar System’s frontier, beyond Neptune. But the claim looks increasingly shaky, after a team of astronomers reported last week that the orbits of a handful of distant lumps of rock are not bunched together by the gravity of “Planet Nine,” as its proponents believe, but only seem clustered because that’s where telescopes happened to be looking.

A new way to look for life-sustaining planets
It is now possible to capture images of planets that could potentially sustain life around nearby stars, thanks to advances reported by an international team of astronomers in the journal Nature Communications.

Potentially habitable exoplanet candidate spotted around Alpha Centauri A in Earth's backyard
The nearest solar system to our own may actually host two potentially life-supporting planets, a new study reports. In 2016, scientists discovered a roughly Earth-size world circling Proxima Centauri, part of the three-star Alpha Centauri system, which lies about 4.37 light-years from Earth. The planet, known as Proxima b, orbits in the "habitable zone," the range of distances from a star at which liquid water could exist on a world's surface. (A second planet, Proxima c, was later discovered circling the star as well, but it orbits farther away, beyond the habitable zone's outer limits.)

Astronomers measure enormous planet lurking far from its star
Scientists aren’t usually able to measure the size of gigantic planets, like Jupiter or Saturn, which are far from the stars they orbit. But a UC Riverside-led team has done it.

Hubble pins down weird exoplanet with far-flung orbit that behaves like the long-sought 'Planet Nine'
A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: A hypothesized, distant body in our solar system dubbed "Planet Nine." This is the first time that astronomers have been able to measure the motion of a massive Jupiter-like planet that is orbiting very far away from its host stars and visible debris disk. This disk is similar to our Kuiper Belt of small, icy bodies beyond Neptune. In our own solar system, the suspected Planet Nine would also...

A giant black hole keeps evading detection and scientists can't explain it
An enormous black hole keeps slipping through astronomers' nets. Supermassive black holes are thought to lurk at the hearts of most, if not all, galaxies. Our own Milky Way has one as massive as 4 million suns, for example, and M87's — the only black hole ever imaged directly — tips the scales at a whopping 2.4 billion solar masses.

Asteroids Crashing Into Dead Stars are Helping Explain Where the Universe's Missing Lithium Went
What happened to all the lithium? The question has stumped astronomers for decades. While cosmologists have successfully predicted the abundance of the other light elements from the Big Bang, lithium has always come up short. Now, a team of astronomers may have found the reason: lithium-rich asteroids are smashing into white dwarves.
