The supernova remnant (SNR) lies very far away from galactic plane, which is quite unusual.

Astronomers from the Max Planck Institute for Extraterrestrial Physics have spotted a previously unknown supernova remnant (SNR), called “Hoinga.” The remnant was identified in the first all-sky survey performed by eROSITA X-ray telescope.

Launched by ROSCOSMOS on 13 July 2019, eROSITA- an X-ray telescope is part of German-Russian Spektr-RG space observatory.

Hoinga marks the first discovery of a joint venture between Australia and eROSITA, established to investigate the Milky Way in multiple wavelengths, from low frequency radio waves to high energy X-rays.

An international team of scientists led by Dr. habil. Andrzej Niedzielski (astronomer at the Nicolaus Copernicus University in Torun, Poland) has found three exoplanets, orbiting around stars that can be called “the elder sisters of our Sun.”

While working on this subject for years, and with the help of precise observations of the sky, the team managed to find twenty six stars with exoplanets around them.

With stars mostly red giants, these planetary systems are way older than our own Solar System…


Scientists claim to have finally found a crushed stellar core from a star explosion that was witnessed on 24 February 1987.

On 24 February 1987, scientists witnessed a star exploding into one of the brightest supernova in more than four hundred years.

The mighty supernova was named Supernova 1987A or SN 1987A and it blazed with the power of hundred million Suns for several months after it was first detected.

SN 1987A created quite a buzz with its spectacular light show and quickly became one of the most studied object in the Earth’s sky.

The supernova is located in the…

Martian moons Phobos and Deimos are thought to be the two fragments of what was once a way larger Mars’ moon which was shattered due to a massive collision, happened sometime between one and 2.7 billion years ago. (Artist’s representation)

Phobos and Deimos, the two Martian moons are relatively small as compared to Earth’s moon.

Phobos is about twenty two kilometres in diameter and Deimos is just about twelve kilometres in dia. Both the moons were discovered in 1877 by Asaph Hall.

Their cratered surfaces and carbonaceous chondrite composition suggest that they may have been asteroids that got captured into Martian orbit. The unstable orbit of Phobos points towards the more recent capture.

But, both the moons are in almost circular orbits, near the equator, which is highly unusual for captured asteroids. …

Found inside the huge clouds in the hearts of galaxies, molecular gas is the essential building material for the formation of new stars. Galaxies evolve and form new stars by continuously acquiring this gas.

Star formation is the principle governing factor for galaxy evolution. Without the molecular gas, new stars won’t form and galaxy will stagnate.

It’s long been known that larger galaxies strip off the atomic gas from the outer regions of smaller galaxies. But until now it wasn’t tested with the molecular gas in same detail.

Now, according to a recent research, the smaller galaxies also hold less…

Artist’s impression of comet fragment entering Earth’s atmosphere

About sixty six million years ago a huge piece of rock crashed into Earth at the coast of Mexico. The impact wiped out almost seventy five percent of life forms from the face of the planet, including the dinosaurs.

The space rock (about 11 to 81 kilometres in diameter) is known as Chicxulub impactor or K/Pg impactor. The impact created a 150 kilometres wide and about 20 kilometres deep crater near the present-day town of Chicxulub, Mexico.

While the exact nature of the space rock is still a mystery, but the impactor is typically estimated to have been an asteroid…

The artist’s representation of the galactic X-ray binary source Cygnus X-1 system. The system hosts the most massive stellar-mass black hole (21.2 solar masses) ever detected without using the gravitational waves. The black hole is locked in a tight orbit around its binary companion- a blue supergiant star called HD 226868. Credits: International Centre for Radio Astronomy Research.

New observations of the black hole (also one of the closest black holes to Earth) ever detected have revealed that it is at least fifty percent more massive than previously calculated.

With this sharp increase, the stellar-mass black hole in the X-ray binary system Cygnus X-1 is now openly challenging scientists to rethink their current models of stellar evolutions.

Discovered in 1964, Cygnus X-1 is a galactic X-ray source in the constellation of Cygnus. Shortly after its discovery, it became the subject of a friendly wager between physicists Stephen Hawking and Kip Thorne.

Cygnus X-1 was the first X-ray source…

Artist’s representation of Planet nine. Neptune’s orbit is shown as a tiny ellipse around the Sun.

The existence of Planet nine- a hypothetical planet in the cold outer regions of our Solar System, has always been a hotly debated topic.

The idea behind the Planet nine came after strange clustering of objects lying far beyond the planet Neptune was detected in 2016. These objects are known as Extreme Trans-Neptunian Objects or ETNOs in short.

As of today no observations of any such planet had been announced.

Yet many believe that Planet nine does exist and we haven’t been able to detect it due to its massive distance from the Earth, and also it lies in deep…

Astronomers recently spotted an exoplanetary multi star system where two exoplanets are orbiting backward around their star.

The exoplanets are roughly located at 897 light years from us. The system is called K2–290 and it consists of three stars and two exoplanets, that are in orbit around its main star K2–290 A.

Mostly, in planetary systems (such as our Solar System), the planets and their stars rotate in the same direction. As both (the stars and the planets) eventually form from the same spinning molecular cloud.

However, system K2–290 doesn’t seem to follow this theory. There are two exoplanets in…

After spending many months in quiet space, NASA’s 2020 Mars rover Perseverance will reach Mars on 18th February 2021.

The probe will attempt to land in a crater called Jezero where it is suppose to look for evidence of ancient Martian life.

But here’s the thing: the whole process of entry, descent and landing (EDL) on Martian surface is not as easy as it sounds. In fact, because of the complexities involved, engineers referred it as the “seven minutes of terror”.

EDL is the shortest and most extreme stage of the Mars 2020 mission. It starts when the probe, travelling…
