First 'exomoon' may have been found

Science
Astronomers have announced the possible discovery of the first known moon outside our Solar System.This "exomoon" is not like any in our cosmic neighbourhood: it's the size of Neptune and orbits a planet the size of Jupiter - but with 10 times the mass.The object was spotted in data from Nasa's Kepler spacecraft, and later observed using the Hubble telescope.Astronomers David Kipping and Alex Teachey have published their results in Science Advances journal.But they say that further observations are needed to understand the distant planetary system."We've tried our best to rule out other possibilities such as spacecraft anomalies, other planets in the system or stellar activity, but we're unable to find any other single hypothesis...

Data suggests scientists have found first known exomoon

Oct. 3 (UPI) -- The existence of a large exomoon orbiting a gas giant located 8,000 light-years form Earth best explains a unique pattern of stellar dimming observed by both Kepler and the Hubble Space Telescope. "We are unable to find any other single hypothesis that explains all the data that we have," astronomer David Kipping told reporters during a phone call earlier this week. Kipping and his colleague Alex Teachey, both researchers at Columbia University, detailed their investigation of the Hubble and Kepler data in a new paper published Wednesday in the journal Science Advances. The duo began their research by surveying 284 Kepler-discovered planets with long orbits. Planets too close to their host stars are less likely to feature moons. Of the 284 candidates, one stood out. The tr...

The Nobel Prize in Physics has been awarded to a woman for the first time in 55 years.Donna Strickland, from Canada, is only the third woman winner of the award, along with Marie Curie, who won in 1903, and Maria Goeppert-Mayer, who was awarded the prize in 1963.Dr Strickland shares this year's prize with Arthur Ashkin, from the US, and Gerard Mourou, from France.It recognises their discoveries in the field of laser physics.Dr Ashkin developed a laser technique described as optical tweezers, which is used to study biological systems.Drs Mourou and Strickland paved the way for the shortest and most intense laser pulses ever created. They developed a technique called Chirped Pulse Amplification (CPA). It has found uses in laser the...
Texans claim first win in overtime over Colts

Texans claim first win in overtime over Colts

Sports
INDIANAPOLIS -- At the end of a wildly entertaining, exhausting overtime test of endurance, Indianapolis Colts first-year head coach Frank Reich wasn't about to settle for a tie. Even when facing fourth-and-4 at his own 43 with just 27 seconds remaining, Reich didn't hesitate. He went for it. And didn't second-guess himself when it backfired. In a game where Andrew Luck set franchise records for passing, his final fateful throw was too low and bounced incomplete. The Houston Texans completed a 24-yard pass to DeAndre Hopkins and spiked the ball to stop the clock, which precipitated Ka'imi Fairbairn kicking a 37-yard field goal with one second remaining in overtime for a stunning 37-34 road victory on Sunday at Lucas Oil Stadium. "We're not playing to tie," Reich said. "We're going for ...
