ESO's VLT Captured Bloodshot Colours of Freakish Skull Nebula
Astronomer predicts that this Nebula was formed when a Sun-like star expelled its outer layers in its old age, leaving behind its naked core - a white dwarf - one of two stars that can be seen at the very centre of NGC 246.
Weird Molecule 'Cyclopropenylidene (C3H2)' Found on the Atmosphere of Saturn’s Moon - Titan And No One Knows How
Closed-loop molecules are important because they form the backbone rings for the nucleobases of DNA, the complex chemical structure that carries the genetic code of life, and RNA, another critical compound for life’s functions.
For the First Time, Direct Water Molecular Deposit Detected on the Sunlit Moon by SOFIA
Sahara desert, in comparison, has 100 times the amount of water than what SOFIA detected in the lunar soil.
Active Volcanoes are Primarily Responsible for Io’s Sulfurous Atmosphere, Astronomer Confirmed
Do you know that Jupiter’s moon were the first objects found to orbit a planet other than the Earth?
NASA Mission to Turn Moon’s Crater Into a Powerful Radio Telescope
It inhales carbon dioxide and exhales oxygen and the homemade liquid oxygen on Mars could supply more than ¾ of the propellant humans need for exploration on the Red Planet.
We Maybe Wrong About Life on Mars
It was on 10 October 1960, then the Soviet Union first tried to launch a spacecraft (only a flyby mission), named Mars 1M No.1 to Mars but the spacecraft …
Three Scientists Shared the 2020 Nobel Prize in Physics for Working on Black Holes
On 6 October 2020, The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2020 sharing one half to Roger Penrose current at the …
A Supermassive Black Hole With Six Galaxies Trapped in Its Gravitational Web
For the first time after the Big Bang- the event by which the universe is believed to came into its existence, astronomers with the help of ESO’s Very Large …
Rotation Curve Method for Determining the Mass of Spiral Galaxies
Rotation curve method, consists in determining the rotation curve of the galaxy and then deriving a density distribution model.
Average Mass of Galaxy by Application of Virial Theorem
The application of Virial Theorem to a cluster of galaxies yields the total mass of the cluster and so the average mass of an individual galaxy in that …
Determining the Mass of Elliptical Galaxies by Velocity Dispersion Method
Measurement of velocity dispersion of stars in the nuclear region with the help of high dispersion spectrograms serves the purpose of estimating the total …
Density Wave Theory of Spiral Arms
In a simpler example, they describe it as the cars move through the traffic jam: the density of cars increases in the middle of traffic jam itself, however, moves more slowly.
Precise Timing of A Black Hole Dance Captured by NASA’s Spitzer Space Telescope
Black holes have long been a mysterious and a special topic for astronomers and also to the layman. This mysterious region in space can not be seen directly …
A Galaxy at 12 Billion Light-Years Away Looks Like Our Milky Way
This signifies that we see it as it was when the universe was just 1.4 billion years old. This is the fascination of astronomical technique and observation.
Gravitational Theory of the Origin of Spiral Structure of Galaxies
Spiral arms are composed entirely of Population I material whereas Population II materials are concentrated more towards the centre.
Magnetic Field Theory of Spiral Arms of Galaxy
Scientists have often relied on gravity to explain their results because measuring celestial magnetic fields is extremely challenging. But the data from SOFIA now compel scientists to consider their role.
What Process Creates and Maintains the Spiral Arms Around Spiral Galaxies?
Those spiral arms can be permanent or at least quasi-permanent and they are filled with the stars which can move in and out of the arms as they orbit through the galaxy.
Classification of Galaxies
Though widely followed by scientific community, Hubble’s classification is not the one and only galaxy classification. W.W. Morgan suggested a classification scheme which is based on the relative contributions of light from population types to the total light.
Astronomer Confirmed that the Intermediate Black Hole Exists
[Naming of the gravitational wave; GW190521 gravitational waves are named according to the recorded by LIGO and Virgo on 2019, May 21].
Why Planets like Neptune and Uranus Rains Diamonds?
It has been already predicted that about a depth of 7,000 km, a condition may present at Neptune such that methane decomposes into diamond crystals and rain downwards like hailstones.
