Six more radio signals from deep space deepen mystery …
A total of 17 such radio signals — called fast radio bursts (FRBs) — have been received from this location in space since their discovery in 2007.
Scientists have discovered six more bursts of radio signals coming from a place in deep space outside our galaxy from where similar signals were detected earlier this year and in 2012. Continue reading Radio signals from deep space: Are we being hailed by intelligent beings?
The star KIC 8463853 has a dark secret. Literally. In 2011 and 2013, the light from this star plummeted by as much as 20 percent, suggesting that something very big must be blocking the light. Like, something 20 times the size of Jupiter. Scientists have speculated that comets, gobs of dust, or even a large alien structure could be causing the dimming, but so far, none of the explanations really works.
Now, a paper that was just published to the arxiv has found that the star dimmed by an unprecedented amount over the whole four years that the Kepler telescope kept an eye on it. It’s not known whether this phenomenon is connected to the huge but short-duration dips from 2011 and 2013.
