UY Scuti Reigns as the Universe’s Biggest Known Star, but Its Crown May Be at Risk
UY Scuti, a red hypergiant about 1,700 times the Sun’s radius, is the universe’s largest known star. Nearly 5 billion suns could fit inside its volume, but rivals like NML Cygni and Westerlund 1-26 challenge its claim to the crown. Astronomers stress that size estimates carry large uncertainties, leaving the title of biggest star still conteste...

Habitable Zone Explained: The ‘Goldilocks Zone’ Where Life-Friendly Planets May Exist
The habitable zone, or “Goldilocks zone”, is the region around a star where conditions allow liquid water to exist. Varying with star type, this zone is key in the search for life. Earth’s location in the Sun’s habitable zone has made life possible, and astronomers seek similar rocky exoplanets in other systems to explore the possibility of...

Biggest-Ever Black Hole With Mass Of 36 Billion Suns Discovered: 'Cosmic Behemoth'
The gigantic black hole's size is close to the theoretical upper limit of what is possible in the universe.

Astronomers Detect Black Hole 36 Billion Times the Sun’s Mass, Among Largest Ever Found
Astronomers have detected a dormant black hole with a mass equal to 36 billion Suns in the Cosmic Horseshoe system, 5 billion light-years away. Identified via gravitational lensing and stellar motion, it ranks among the largest known black holes. The discovery sheds light on the link between galaxy size and central black hole growth.

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...

NASA Hubble Space Telescope Helps Confirm the First Solitary Black Hole
In the Sagittarius constellation, a lone and first-ever solitary black hole has been discovered by a team of scientists. Although the discovery began in the year 2011, the observations have confirmed it recently. The size of this black hole is as massive as seven times of the sun. Despite the conflicts and differences of observations by another tea...

James Webb Space Telescope Detects Supernova From 11.4 Billion Years Ago
Astronomers using the James Webb Space Telescope (JWST) have identified AT 2023adsv, a supernova that occurred 11.4 billion years ago. This stellar explosion, from a star 20 times the size of the Sun, offers a glimpse into the early universe's unique stellar evolution. Part of the JWST Advanced Deep Extragalactic Survey, the event highlights how th...

Scientists Predict Ultramassive Black Holes Can’t Grow Beyond 100 Billion Suns
Scientists led by Dr Priyamvada Natarajan from Yale University have discovered that ultramassive black holes likely cannot exceed 100 billion solar masses. These giants regulate their own growth by emitting gas jets that heat and expel surrounding material, cutting off their gas supply. Additionally, the team is exploring intermediate-mass black ho...

First Zoomed-in Picture of a Star Outside Our Galaxy Captured, Revealed to Be a Dying Star
The first detailed image of a star outside the Milky Way reveals WOH G64, a giant nearing its end. Captured by the Very Large Telescope Interferometer, this dying star, 1,500 times the size of the Sun, is surrounded by a cocoon of gas and dust, hinting at its eventual collapse into a supernova.

NASA's Parker Solar Probe To Have Final Venus Flyby Today Ahead Of Historic Sun Encounter
The Parker Solar Probe was launched in 2018 on the mission to "touch" the Sun. It is just about the size of a small car.

New Group of Distant Objects Suggests Our Solar System May Have a Second Kuiper Belt
Astronomers have discovered 11 objects beyond the Kuiper Belt, suggesting the existence of a second belt, dubbed "Kuiper Belt 2." Located between 70 and 90 AU from the sun, this new region could redefine our understanding of the solar system's size and structure. The discovery was made using the Subaru telescope in collaboration with NASA’s New H...

NASA Might Have Spotted Highest Number of Sunspots in Over 20 Years
On August 8, 2024, NASA's Solar Dynamics Observatory (SDO) may have documented a record-breaking number of sunspots in a single day, marking a significant event in Solar Cycle 25. These sunspots, which are dark, cooler areas on the Sun’s surface caused by intense magnetic activity, play a crucial role in the Sun's behaviour and have a direct impa...

2 Scientists Claim That The Sun Is Fractionally Smaller Than We Thought
Two astronomers have found evidence that the radius of our Sun is a few hundredths of a percent slimmer than previous analyses indicated.

Supermassive Black Hole Spotted Eating Sun-Like Star in Nearby Galaxy
Black holes, celestial objects known for their gluttony, usually eat stars unlucky enough to stray too close to them in one big gulp, annihilating them with their enormous gravitational pull. But some, it turns out, tend to snack rather than gorge. Researchers said they have observed a supermassive black hole at the center of a relatively nearby ga...
