Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis
Hubble Space Telescope’s recent observations of FU Orionis have revealed surprising new details about the star’s accretion disk. The study found that the disk’s inner edge reaches temperatures as high as 16,000K, nearly three times hotter than the Sun’s surface. This discovery challenges existing models of stellar accretion, which had predi...

Scientists Scan TRAPPIST-1 for Interplanetary Radio Signal Using Allen Telescope Array
Scientists at Penn State and the SETI Institute have developed a new method to search for interplanetary radio signals from planets in the TRAPPIST-1 system. Using the Allen Telescope Array, they scanned this system for nearly 28 hours but did not find evidence of alien communication. This project, however, has introduced a new way of detecting pot...

Jupiter Has An Identical Twin, 17,000 Light-Years Away
Astronomers have discovered a planet that is nearly identical to Jupiter, circling a star 17,000 light-years away from the Earth.

Can Dying Stars Give Birth to New Planets? Here’s What Scientists Have to Say
Scientists now say it is not necessarily the only possibility. They say planets can form even if a star is nearing its death, long after the star was formed. Dying stars leading to the formation of planets is a completely new theory. If confirmed, this finding can change how we understand the functions of the universe and planetary evolution.

Scientists Find 'Largest Cluster' of Nearly 100 Free-Floating Planets in a Single Star-Forming Region
Rogue planets have baffled astronomers for ages. Unlike regular planets which revolve around stars, these free-floating planets (FFPs) get ejected from star systems to move about in the galaxy on their own. In the latest discovery, astronomers found the largest cluster of rogue planets in a single star-forming region.

How Close Will Jupiter, Saturn Come Today In About 400 Years? See Here
Great Conjunction: The Jupiter and Saturn appear to pass each other nearly once every 20 years but what is so extraordinary about today's celestial extravaganza? The NASA says, "It's been nearly 400 years since the planets passed this close to each other in the sky'.

Astronomers Discover 100 New "Cool Worlds" Near The Sun
Astronomers and a team of data-sleuthing volunteers participating in Backyard Worlds: Planet 9, a citizen science project, have discovered roughly 100 cool worlds near the Sun -- objects more massive than planets but lighter than stars, known as brown dwarfs.

Planets Around Nearby Star Intrigue Astronomers In Search For Alien Life
Up to three planets - potentially rocky like Earth - have been spotted around a star located relatively near our solar system - a planetary system offering astronomers intriguing possibilities in the search for signs of extraterrestrial life.

Scientists Discover Habitable 'Super-Earth' Among 15 New Planets
Scientists have discovered 15 new planets - including one 'super-Earth' that could harbour liquid water - orbiting small, cool stars near our solar system.

NASA's Hubble Telescope Detects Giant 'Cannonballs' Shooting From Unseen Star
NASA's Hubble Space Telescope has detected mysterious stellar "cannon fire" - superhot blobs of gas, each twice as massive as the planet Mars, being ejected at a very high speed near a dying star, say scientists including one scientist of Indian origin.

Planet 8 Times Bigger Than Jupiter Found Near Very Young Star
Astronomers have discovered a giant planet, at least eight times larger than Jupiter, that orbits a 2 million-year-old star about 450 light years from Earth, contradicting a long-standing idea that larger planets take longer to form.

Astronomers Spot Widest Solar System: Study
Astronomers have found the widest-known solar system, with a huge planet so far from its star that it takes nearly a million years to complete an orbit, according to a new study.
