Hubble Space Telescope Captures Rare Edge-On View of a Spiral Galaxy Located Millions of Light-Years Away
NASA and ESA’s Hubble Space Telescope captured an edge-on view of spiral galaxy UGC 10043, located around 150 million light-years away. Displaying its prominent dust lanes and unique bulge, this galaxy image highlights regions of active star formation. Captured in 2000 and 2023, the composite image uses various light wavelengths to detail the str...

Hubble Telescope Reveals Milky Way Blowing Gas off LMC Galaxy in Close Encounter
NASA’s Hubble Space Telescope has captured an extraordinary phenomenon as the Milky Way galaxy exerts ram pressure on the Large Magellanic Cloud (LMC), stripping away most of its gas halo. The interaction, which occurs as LMC passes near the Milky Way, has led to the loss of significant mass from the dwarf galaxy. Despite this, LMC retains enough...

Cosmic Survey Reveals Surge of Black Holes in Dwarf Galaxies
A cosmic survey using the Dark Energy Spectroscopic Instrument has identified over 2,500 active black holes in dwarf galaxies, tripling previous estimates. Conducted by the University of Utah’s Ragadeepika Pucha, the research has also uncovered nearly 300 intermediate-mass black holes, quadrupling their known population. This milestone discovery ...

Indian Scientists Find Dwarf Galaxy Radio Jet Interacting With Interstellar Gas
Scientists at the Indian Institute of Astrophysics (IIA), an autonomous institute of the Department of Science and Technology (DST), have discovered interaction between a radio jet from a dwarf galaxy and interstellar gas causing shock waves.

A Third of Milky Way’s Planets Orbiting Most Common Stars Could Hold Water, Harbour Life: Study
One-third of the planets orbiting the most common stars across the Milky Way galaxy may hold onto liquid water and possibly harbour life, according to a study based on latest telescope data.

Scientists Discover New Black Hole That Devoured Nearby Star In Neighbouring Galaxy
An undetected intermediate-mass black hole lurking in a dwarf galaxy revealed itself to astronomers when it devoured an unlucky star that got too close.

Pegasus V, Dwarf Galaxy Near Andromeda, Believed to Be One of the First Galaxies
A team of astronomers at the University of Surrey recently found an extremely faint, dwarf galaxy which, they believe, is one of the first galaxies packed with a very old star. The galaxy, monikered as Pegasus V, is located in the vicinity of the Andromeda galaxy. The “fossil” galaxy that the team discovered has a high concentration of old star...

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.

Distant Dwarf Galaxy Formation Spotted by Research Team With Indian Scholar
A research team including astronomers from the US, India and France have studied the formation of new stars beyond the visible boundaries. The team is yet to understand how the dwarf galaxies of the past have evolved into the ones in the present day. The team includes Indian scholar Anshuman Borgohain from Tezpur University.

Distant Dwarf Galaxy Formation Spotted, Indian Researcher In Study Team
A first of its kind study has found new stars forming beyond the visible boundaries about 1.5 to 3.9 billion light years away from the Earth, according to an article by a research scholar of Tezpur University.

Meet the 'Zombie Star', Residing in Spiral Galaxy NGC 1309, That Survived Supernova Blast
Astronomers have observed a star that not only survived a stellar explosion called a supernova, but emerged from it brighter than before the blast. This white dwarf is gravitationally locked in orbit with another star — a pairing called a binary system.

Teenage Pulsar Reveals Itself to Astronomers, Possibly the Strongest Ever to Be Identified
Astronomers have made an exciting new discovery, identifying a newborn pulsar that may possibly be only 14 years old. Scientists were finally able to observe the pulsar after the dense debris and bright energy emissions from the supernova explosion that created the pulsar finally thinned enough.

Strange Repeating Fast Radio Burst (FRB) Originating From Distant Galaxy Detected by Scientists
The detection of a new and strange fast radio burst originating from a galaxy located 3 billion light-years away has left astronomers puzzled. Fast Radio Burst or FRB are bursts of radio waves in space that are milliseconds long. The latest finding has caused the astronomers to speculate if there are two kinds of fast radio bursts.

Astronomers Discover Hidden Trove of Massive Black Holes, Can Help Understand the Milky Way’s Origin
A group of researchers has found a previously overlooked trove of massive black holes in dwarf galaxies. These black holes, the researchers believe, can offer insights into the journey of the supermassive black hole that sits at the centre of the Milky Way.
