They travel at a speed of 1.5 million miles per hour. • 2010 : The term cold fusion coined in 1989 by Martin Fleishmann and Stanley Pons claimed to have achieved when nuclear fusion at room temperature begins to gain currency . Regarded at the time as junk science , at the present time , there is interest in it, as is clear from the papers presented at the 239 meeting of the American Chemical Society ( ACS). • 2010 : Astronomers find most distant galaxy with intense star formation activity . The galaxy SMM J2135 - listed as 0102, is 10 billion light-years from us, a redshift of 2.3. • 2010: Akatsuki space probe Aerospace Exploration Agency of Japan , JAXA , intended to travel to the planet Venus, above the Tanegashima space center in southern Japan . • 2012: Launch of Kanopus - V -1, Belka , Zond -PP, ADS- 1B and TET -1 satellite using a rocket from Baikonur Soyuz-FG/Fregat . • 2013 : NASA announces that substantially reduce its public outreach mechanisms . • 2013: A team of researchers presented the first discovery of a Trojan Uranus : the object 2011 QF99 ranging around the Lagrangian point L4 of Uranus.
