Astronomers discovered three planets which have similar sizes and temperatures those of Venus and Earth
This was found using the TRAPPIST telescope at ESO’s La Silla Observatory. 
•    The discovery was published in the Journal Nature on 2 May 2016.
•    Ultra-cool dwarf star 2MASS J23062928-0502285, now also known as TRAPPIST-1.
•    They found that the dim and cool star faded slightly at regular intervals which indicated that several objects were passing between the star and the Earth.
•    On the detailed analysis, it showed that three planets are present around the star.
•    It is much cooler and redder than the Sun and barely larger than Jupiter.
•    Despite being so close to the Earth, the star is too dim and too red to be seen with the naked eye or even visually with a large amateur telescope.
•    Two of the planets have orbital periods of about 1.5 days and 2.4 days respectively, and the third planet has a orbital period in the range 4.5 to 73 days.

Russia has launched the first rocket from its newly built Vostochny Cosmodrome in the Amur Oblast, in Russian Far East region bordering China. 
•    The rocket is carrying three satellites with it namely Mikhailo Lomonosov , SamSat-218 and Aist-2D. 
•    Vostochny Cosmodrome is a Russian spaceport for civilian launches which is still under construction. 
•    Presently, Russia has the large military launch facilities.
•    But for launch but it has to depend on the Baikonur Cosmodrome for the civilian launches.
•    The new cosmodrome is going  to enable Russia to launch most missions from its own land.
•    Currently, Baikonur is the only launch site operated by Russia with the capability to launch crewed missions to ISS or elsewhere.
•    Seven launch pads are planned to be built at Vostochny, over a period of years.
•    Construction of the cosmodrome began in January 2011 and, as of 2011, was expected to be completed in 2018.
