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...

"Orange Like The Sun": Tourists Rush To Iceland's Latest Volcanic Eruption
The eruptive faults reached a total size of around 900 metres overnight, compared with 200 to 300 metres initially, according to the latest update from the Icelandic Meteorological Office (IMO) Tuesday.

James Webb Telescope Finds Evidence Of ''Celestial Monster'' Stars The Size of 10,000 Suns
These ''celestial monsters'' are 5000 to 10000 times more massive and five times hotter at their centre than the Sun.

Supermassive Black Hole 33 Billion Times The Size Of Sun Discovered By UK Astronomers
Durham University scientists said this is one of the biggest ever black hole found.

Researchers Estimate Size of Largest Known Star Through Sharpest Optical Image Ever Captured
R136a1, a massive star with a mass around 150 or 200 times the Sun, has been observed in great detail, along with other stars in the cluster. The images from Gemini South's Zorro instrument have provided scientists with the clearest images of the star so far, which suggest it may not be as massive as previously thought.

Chandra X-Ray Observatory Reveals Information on the Events Around a Rejected Star
Data received from the US space agency NASA's Chandra X-ray Observatory has revealed some fascinating features of a star, which was likely ejected from its birthplace due to a powerful explosion. The star, Zeta Ophiuchi, has a complicated past and is located some 440 light-years from Earth.

Massive Earth-Facing Sunspot Rapidly Increases in Size, May Result in Auroras
In what could result in some magnificent auroras or Northern Lights, a spot on the surface of the Sun has been growing at a rapid pace and has become three times the size of Earth. The sunspot, Active Region 3038 (AR3038), has been found to be facing our planet and can probably emit some solar flares. The sunspot expanded more than double in size i...

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.

Giant Sunspot Doubled in Size in Just 24 Hours, Is Now Directly Pointing at Earth: Researchers
A sunspot, called AR3038, grew to almost twice the size of Earth. In the span of 24 hours, its diameter swelled to double its own size. The sunspot is 2.5 times the size of Earth and is facing directly at our planet.
