The study which has been published in journal nature said that after running out of fuel in its core, the star began to grow in size, shrinking the gap with its neighbhouring plant, eventually swallowing it.
Dubbed as 'Hycean' -- hot, ocean-covered planets with hydrogen-rich atmospheres, the new class of exoplanets are more numerous and observable than Earth-like planets, and can support life, said astronomers from the University of Cambridge in the UK.
Nine star-like objects that appeared and vanished in a small region within half an hour on an old photographic plate, were discovered by astronomers.
The rare Wolf-Rayet stars are highly luminous objects a thousand times that of the Sun and have intrigued astronomers for long, the Union Ministry of Science and Technology said in a statement on Tuesday.
High-velocity stars can provide deep insights into a wide range of topics within galactic science, from the central supermassive black hole to the distant galactic halo, according to Lu Youjun, a researcher at the NAOC.
Astronomers have discovered the brightest infrared light from a short gamma-ray burst ever seen, with a bizarre glow that is much brighter than previously thought was possible.
The composition of the Moon's near side that is perpetually Earth-facing is oddly different from its far side which always faces away from Earth and scientists think they finally understand why.
According to the astronomers, triple eclipses are very rare as compared to the double or single eclipse. Between June 5 and 6, a penumbral lunar eclipse will occur, which will then be followed by an annular solar eclipse on June 21 and another lunar penumbral eclipse on July 5.
The SCISAT satellite was developed by the Canadian Space Agency to help scientists understand the depletion of the Earth's ozone layer by looking at particles in the atmosphere as sunlight passes through them. With its help, the study says, astronomers can tell what molecules are found in a planet's atmosphere by observing the changes in starlight as it shines through the atmosphere.
The study also provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.
The main object, referred to as MM 1a, is a young massive star surrounded by a rotating disc of gas and dust that was the focus of the scientists' original investigation.
The system was nicknamed Apep. Two of Apep's stars are of the Wolf-Rayet variety meaning they are massive and reaching the end of their life.
According to co-author Andrew Casey, it was previously believed that the first stars that formed in the universe could not possibly still exist today.
The fact that the most powerful jets are associated with binary black holes could have important consequences for the formation of stars in galaxies.
Over the past three decades, the search for dark matter has focussed mostly on a class of particle candidates known as weakly interacting massive particles (WIMPs).
A first confirmed image of a planet forming in the dust swirling around a young star has been captured.
The scientists tracked the event with radio and infrared telescopes, in a pair of colliding galaxies 150 million light-years from Earth.
These black hole couples formed when two galaxies merged with each other after collision, forcing their supermassive black holes close together.
An analysis has found that the powerful winds that make up for the swirling atmosphere on Venus gain strength on the darker side of the planet
A team of astronomers led by an Indian-origin researcher have spotted the smallest asteroid ever characterised – a tiny space rock measuring two metres in diameter. The asteroid, named 2015 TC25, is also one
