ASTRONOMY & SPACE SCIENCE

Launched on 30th July 2020, Perseverance rover has successfully landed on the Mars surface at Jezero Crater on 18th February 2021, after travelling almost seven months from Earth. Designed specially to collect sample of rocks, Perseverance is the biggest and the best rover ever...
Solar wind, the stream of electrically charged particles emanating from the outer atmospheric layer corona of Sun, poses threat to life form and electrical technology based modern human society. Earth’s magnetic field provide protection against the incoming solar wind...
The Nebra Sky Disk has inspired the logo of the space mission ‘Cosmic Kiss’. This space mission of the European Space Agency is the declaration of love for space. Ideas from observation of night sky played important role in religious beliefs...
The seven planets in the stellar system of TRAPPIST-1 are similar in densities. Stars in the galaxies have stellar systems comprising mainly of their planets and satellites. For example, our home stellar system viz. solar system has nine planets...
The researchers from the Sloan Digital Sky survey have reported most detailed look at the warp of our home galaxy   Usually, one think of spiral galaxies as a flat disc rotating around its centre but about 60-70% of the spiral galaxies including...
NASA recently released the spectacular bright image of the firework galaxy NGC 6946 taken earlier by Hubble space telescope (1)   A galaxy is a system of stars, remnants of stars, interstellar gas, dust, and dark matter that are bound together...
PHILIP: Laser-Powered Rover to Explore Super-Cold Lunar Craters for WaterHuman settlements beyond Earth on Moon or on planets like Mars in space have long been the theme of science fiction. However, serious thoughts and research activities towards this have...
Astronomers usually get to hear from the far-off galaxies through high energy radiations like X-rays. It is extremely uncommon to receive relatively lower energy UV radiation from ancient galaxies like AUDs01. Such low energy photons usually get absorbed on...
NASA’s ambitious mars mission Mars 2020 was successfully launched on 30 July 2020. Perseverance is the name of the rover.   The main task of Perseverance is to seek signs of ancient life and collect rock and soil samples for possible return to Earth.  Mars is cold, dry...
NASA’s infra-red observatory Spitzer has recently observed the flare from gigantic binary black hole system OJ 287, within the estimated time interval predicted by the model developed by astrophysicists. This observation has tested different aspects of General Relativity, the...
Though data from orbiters have suggested presence of water ice, the exploration of lunar craters in the polar regions of moon has not been possible due to the absence of suitable technology to power lunar rovers in the perpetually...
X-ray and radio observation of galaxy system Abell 2384 reveals collision of two galaxy clusters that travelled through each other forming a binodal system with a bridge of superhot gas between two cluster lobes and a bend in the...
The Belgian satellite PROBA-V, developed by European Space Agency has completed 7 years in orbit providing daily data on the state of vegetation at the global scale. The Belgian satellite PROBA-V, developed by ESA on the initiative of Belgium has...
T2K, a long-baseline neutrino oscillation experiment in Japan, has recently reported an observation where they have detected a strong evidence of a difference between fundamental physical properties of neutrinos and that of the corresponding antimatter counterpart, anti-neutrinos. This observation...
Astrobiology suggest that life is abundant in the universe and the primitive microbial life forms (beyond earth) could be found earlier than intelligent forms. The search for the extra-terrestrial life involves looking for biological signatures in the vicinity of...
Scientists have successfully taken first ever picture of the shadow of a black hole providing direct observation of its immediate environment Image taken from "EHTC, Akiyama K et al 2019, 'First M87 Event Horizon Telescope Results. I. The Shadow of...
A pair of astronomers have made the big discovery of an ‘exomoon’ in another solar system Moon is a celestial object which are either rocky or icy and there is a total of 200 moons in our solar system. This...
A “sibling” of Earth’s galaxy Milky Way is discovered which was torn apart by Andromeda galaxy billions of years ago Our planet Earth is part of the solar system which comprises eight planets, numerous comets and asteroids which orbit the...
