James webb Space Telescope: JWST is going to give us our first detailed glimpse of our early universe from which we and everything we know was born. It is a 10-billion-dollar endeavour. It is the successor of Hubble Space Telescope and optimised for Infrared wavelengths. Hubble was the first telescope that was established in space and does Optical and near Infrared imaging. It has done some game changing discoveries in 25 years of life span like find finding exoplanet, super massive black hole, saw collision & merging and growth of galaxies. In spite of all these achievements Hubble has one flaw that it can’t observe some place of universe, we need more powerful telescope than Hubble. So JWST comes in picture. JWST is a joint venture of NASA, ESA (European Space Agency), CSA (Canadian Space Agency). JWST was expected to be launched on 2007 but after 16 launch delays it finally launched by Ariane 5 (European heavy lift launch vehicle) from the European spaceport in Kour...
U sually when star like sun die means run out of fuel, will pull nearby asteroids and planets inward and crushed them and will create a disk of debris that surrounds the planet. But this is first planet that made the whole journey intact. NASA researchers announced last week that they have discovered a planet orbiting a white dwarf star and that is confirmed by NASA's satellite TESS ( Transiting Exoplanet Survey Satellite ) and Spitzer Space Telescope . Planet named WD 1856 b orbiting a small white dwarf star ( WD 1856 ) which is 80 light years away from Earth in Draco Constellation. The planet WD 1856 b, is a gas giant roughly the size of Jupiter and carry 14 time more mass from Jupiter. Star containing sun's half mass and size slightly larger than earth. According to NASA, it circles the star very closely and makes a complete orbit about every 34 hours. Vanderburg says in the NASA statement "WD 1856 b got very close to its white dwarf and managed to stay in one piece...
