Five Dwarf Galaxies Found in a Rare Alignment, Challenges Current Cosmic Models
A rare alignment of five dwarf galaxies, positioned around 117 million light-years away, has been discovered by astronomers. This grouping, which challenges existing models of galaxy formation, shows active star formation despite their small sizes. The galaxies, labelled D1 to D5, exhibit unique characteristics, including shared rotational motion a...

Jupiter’s Moon Io Shows No Magma Ocean as New Findings Explain Volcanic Eruptions
NASA's latest findings indicate that Jupiter's volcanic moon Io does not have a global magma ocean beneath its surface, debunking previous theories. This conclusion comes from analysis of data from NASA's Juno spacecraft and archival observations from the Galileo mission. The study suggests that Io's interior is more solid than expected, with volca...

Indian Ocean Gravity Hole Might Have Been Formed After the Death of an Ancient Ocean
A vast anomaly in the Indian Ocean, called the gravity hole, has been studied for decades due to its weak gravitational pull and significantly lower sea levels. Recent findings link its origins to the ancient Tethys Ocean and mantle changes caused by tectonic plate shifts. Researchers used advanced models to simulate the geological processes, revea...

Earth's Temporary Second Moon: Asteroid 2024 PT5's Two-Month Orbit Explained
Asteroid 2024 PT5 will soon become Earth’s temporary second moon, entering orbit on September 29 and departing by November 25. While this mini-moon won't complete a full orbit, it will be caught in Earth’s gravitational pull for nearly two months. Unlike other celestial objects, this asteroid will be too dim to observe without advanced equipmen...

NASA Citizen Scientists Discover Mysterious Object Moving out of Milky Way at an Extremely High Speed
On August 15, 2024, NASA’s Backyard Worlds: Planet 9 project, featuring the contributions of dedicated citizen scientists, made a groundbreaking discovery: an object moving at an astonishing speed of 1 million miles per hour, which will soon escape the gravitational pull of the Milky Way. This hypervelocity object, catalogued as CWISE J124909.08+...

The Earth Is Not Revolving Around The Sun But Something Else Nearby. NASA Explains What It Is
New insights into planetary motion reveal that Earth is not technically orbiting the Sun. Instead, both the Sun and Earth revolve around a shared centre of mass called the barycentre.

Our Solar System Will Eventually Be "Crushed And Ground To Dust", Study Finds
Solar Eclipse 2024: The Sun gives energy to life on Earth, and without this star, we wouldn't be here. But even stars have limited lifetimes, and someday our Sun will die and our planet will be swallowed by it before it becomes a white dwarf.

As Hurricane Idalia Heads Towards Florida, Rare Blue Supermoon Could Worsen Tides
Known as a king tide, these higher tides are caused by the extra gravitational pull that occurs when the sun and moon align with Earth.

As Chandrayaan-3 Prepares for Landing, Experts Explain Moon's Many Mysteries
The Moon has captivated human curiosity for centuries, and with each new mission, we uncover more about its geological history, composition and potential for scientific discovery. As anticipation grows for India's planned Chandrayaan-3 lunar landing on Wednesday, an expert delves into the fascinating world of Moon exploration.

Dwarf Galaxies of Earth’s Second Closest Galaxy Cluster Devoid of Dark Matter Halos
In a study led by the University of Bonn and the University of Saint Andrews (Scotland), astronomers suggest that the dark matter halos are absent from the dwarf galaxies in the Fornax Cluster, the second closest galaxy cluster to Earth. The findings were published in the Monthly Notices of the Royal Astronomical Society.

Tidal Event Analysis Suggests Black Hole Ripped Apart Star, Sent Its Material Out in Space
In a recent observation, it was established that during a tidal even called AT2019qiz, a black hole not only ripped apart the star and stretches its material, but also threw some intense wind flowing outward, sending the star's material out into space. While black holes are known to engulf the cosmic bodies, this research is crucial for understandi...

Black Hole Hunters Cast Gaze At Center Of The Milky Way Galaxy
Residing at the center of our spiral-shaped Milky Way galaxy is a beast - a supermassive black hole possessing 4 million times the mass of our sun and consuming any material including gas, dust and stars straying within its immense gravitational pull

Eight New Echoing Black Hole Binaries Discovered in Our Galaxy: MIT Researchers
Black holes are intriguing and mysterious objects. They are dreaded, too, because their gravitational pull is so strong that they do not allow anything to pass through them, not even light, except on the rare occasions when they feed. When a black hole pulls in gas and dust from an orbiting star, it sends out spectacular bursts of X-ray that bounce...

James Webb Space Telescope 'Will Be Orbiting Lagrange Point 2': NASA Explains What It Means
Lagrange points refer to locations where the Earth’s gravitational pull completely balances out the Sun’s much stronger gravity

How Did Heavy Metals Like Gold, Uranium Form? Research Says Answer Lies in Black Holes
While all heavy metals have formed under extreme conditions inside stars or due to stellar explosions and collision of neutron stars, the question remains: when and why was the material ejected and whether heavy elements can be produced in any other way.
