NASA Has A "Huge Announcement" To Make -They found another Earth!!!

NASA is set to announce the major discovery of a new planet by the Kepler Space Telescope tomorrow (July 23) at noon EDT (5 p.m. BST), and you can watch it live below.
Today we know that Earth is just one of hundreds of billions of planets in our galaxy, itself just one of hundreds of billions of galaxies.
But while this knowledge might seem commonplace, it is rather incredible to remember that the first planet outside the Solar System was not discovered until 1992 – and then only byaccident.
Since then, thanks to an array of telescopes we have a greater understanding than ever of some of the exoplanets found elsewhere in the universe – from fascinating hot Jupitersthat orbit their stars in days to Earth-sized planets in habitable zones of red dwarfs – but we are yet to find a true Earth 2.0, namely an Earth-sized world around a Sun-like star.
"Today, and thousands of discoveries later, astronomers are on the cusp of finding something people have dreamed about for thousands of years – another Earth," NASA teased in a statement. The live stream below will reveal the discovery tomorrow at a news conference at noon EDT (5 p.m. BST).No planet-hunter has been more successful than NASA’s Kepler Space Telescope, which has been responsible for finding the vast, vast majority of all the planets we know of today – with its current tally standing at more than one thousand confirmed planets and several thousand more candidates.

Launched in 2009, Kepler's primary mission lasted for more than three years, during which time it monitored more than 145,000 main sequence stars with a photometer. By detecting dips in brightness from orbiting planets passing in front of the stars – known as the transit method – the telescope has been able to find a huge number of worlds.
After losing the use of two of its four reaction wheels in 2013 – which it uses to angle itself towards distant stars – NASA came up with a novel method to continue operations by using the photons from sunlight as a makeshift third reaction wheel. Using this method, Kepler is now in the midst of its second mission, dubbed K2 “Second Light.”
So, tune in tomorrow for news of its latest discovery as we continue to reveal our place in this increasingly planet-rich universe.
From NASA:
NASA will host a news teleconference at 9 a.m. PDT (noon EDT) Thursday, July 23, to announce new discoveries made by its planet-hunting mission, the Kepler Space Telescope.
The first exoplanet orbiting another star like our sun was discovered in 1995. Exoplanets, especially small Earth-size worlds, belonged within the realm of science fiction just 21 years ago. Today, and thousands of discoveries later, astronomers are on the cusp of finding something people have dreamed about for thousands of years -- another Earth.
The briefing participants are:
-- John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington
-- Jon Jenkins, Kepler data analysis lead at NASA's Ames Research Center in Moffett Field, California
-- Jeff Coughlin, Kepler research scientist at SETI Institute in Mountain View, California
-- Didier Queloz, professor of astrophysics at Cambridge University, United Kingdom
Launched in March 2009, Kepler is the first NASA mission to detect Earth-size planets orbiting distant stars in or near the habitable zone -- the range of distance from a star in which the surface temperature of an orbiting planet might sustain liquid water. The telescope has since confirmed more than 1,000 planets and more than 3,000 planet candidates spanning a wide range of sizes and orbital distances, including those in the habitable zone.
Questions can be submitted on Twitter during the teleconference using the hashtag #askNASA.
