 Vanguard 1: The 1st Solar power Satellite Launching date - March 17, 1958 Power mode - Solar electric power  launching vehicle - Three stage launching vehicle                       IMAGE COURTESY- Wikipedia   It was the fourth Artificial satellite in the earth's orbit after Sputnik 1, Sputnik2, Explorers1. It was an American satellite. Satellite lost its contact with the headquarters in 1964 but till today it is orbiting Earth.  Purpose of launching - It was launched for testing a three-stage launching vehicle and the effects of space environment on the satellite along with the effects of Earth's orbit.

 Happy Makar Sakranti to my all viewers with a lots of love and happiness.

 Exoplanets holds a better survival than Earth ■Exoplanets are those planets that have a rocky surface like Earth, Mars etc. and found outside our solar system.  We have heard a term SUPER - EARTH A Super earth is  an extra solar planet with a mass higher than our earth but lower mass than " ice giants" such as Uranus, Neptune. examples of super earth are COROT - 7b{ICARUS}, GJ1214b{SHESHA}, KEPLER - 440b. ■  Reasearchers had already discovered many planets similar to our mother EARTH but very recent studies has opened up new mysterious facts revealed "these SUPER - EARTHS full of Hydrogen and Helium.

    Hubble Space Telescope (HST) ● Launched by - NASA on 24 April 1990. ● Budget   - According to Nasa , HST has cost approximately $16 billion from the beginning in 1977 and this doesn't includes the cost of space shuttle and servicing . ● Size  13.2m long and 4.2 m wide at its back and all instruments in this telescope attached here. ● Weight - 12,246 kg or 27,000 pounds we can assume its size and its weight nearly comparable to a mini bus or a mini truck. ● Used technologies  -    ■ Advanced camera for surveys(ACS)   ■ Cosmis origins spectrograph (COS)   ■ Corrective optics space telescope axial replacement(COSTAR)   ■ Faint object camera(FOC)   ■ Faint object spectrograph (FOS)   ■ Fine guidance sensor(FGS)   ■ Goddard high resolution spectrograph (GHRS/HRS)   ■ High speed photometer(HSP)   ■ Near infrared camera and multi- object spectrometer (NICMOS)   ■ Space telescope imaging spectrograph (STIS) ...

 Research: The mass of a black hole is 4.4 times the mass of sun|Binary systems|black hole NASA  and European Space Agency(ESA) for the first time measured the mass of a black hole moving in space with the one and only The Hubble Space Telescope (HST). Until now the mass of a black hole determined on the basis of position of binary systems or galaxies. Large black holes were belived to occur only with companion stars , but for the first time a single black hole has occured .  The discovered black hole is believed to be about 80 light years away from our galaxy. Earlier it was estimated that it is 5000 light years away. Stars increase its mass by interacting with another star or its comapnion star. When the mass increased it explodes called Supernova.  Remants called as 'neutron star'. When remanant is bery large it is called "black hole".  According to scientists the mass of a neutron star is between 1.6 to 4.4 times the mass of sun. The discoveries till n...
