In a continuing search for other planets that may harbor life, re-analysis of Hubble Space Telescope images from 1998, astronomers have found evidence for two extrasolar planets that went undetected back then. Four giant planets are known to orbit the young, massive star HR 8799, which is 130 light-years away. The first three were discovered In 2007 and 2008. The fourth was spotted in 2010.

The three outer gas-giant planets, discovered with the ground-based Keck Observatory. They weren’t found in 1998 when the Hubble observations were first taken because the methods used to detect them were not available at that time. They have approximately 100-, 200-, and 400-year orbits. This means that astronomers need to wait a very long time to see how the planets move along their paths.

Astronomer Remi Soummer, of the Space Telescope Science Institute in Baltimore, says, "The archive got us 10 years of science right now. Without this data we would have had to wait another decade. It’s 10 years of science for free."

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency (ESA).

Is there anything else that we’re going to rediscover in the future that’s been there all along? will we discover that time travel is real? (Or maybe someone else has ALREADY discovered how to do it!) Sometimes a novel can tell you more than nonfiction, and Whitley Strieber’s novel "Omega Point" is one of these. You can get it from the Whitley Strieber Collection, and it will come with an autographed bookplate that was designed by Whitley!
