Astronomers have traced a series of brief, enigmatic bursts of radio waves to a galaxy far, far away and indeed a long time ago — some three billion years or so. But as much as you might be hoping or dreading it to be true, this is probably not E.T.

“We’ve joked about spaceship battles and death stars blowing up, but we think we can explain it with ordinary physics,” said Shami Chatterjee, a Cornell University astronomer. Shami is the lead author of a paper published in Nature this month that details the search for the source of the radio waves known as “fast radio bursts,” — intense pulses of radiation from the sky lasting only a few milliseconds.

These have been disappointing times for those yearning for some alien direction from Out There. Last summer, Russian astronomers reported that they had recorded a promising-sounding signal from a star in the Hercules constellation, but they dismissed it when it became public as a freak bit of random radio noise, the astrophysical equivalent of a cosmic butt dial. More recently, searches for radio signals from a set of stars with anomalous spectral features and another star known as Tabby’s Star that has shown suspicious variations in its light seem to have come up empty.

WASHINGTON — As President Trump signed a sweeping executive order on Friday, shutting the borders to refugees and others from seven largely Muslim countries, the secretary of homeland security was on a White House conference call getting his first full briefing on the global shift in policy.

Gen. John F. Kelly, the secretary of homeland security, had dialed in from a Coast Guard plane as he headed back to Washington from Miami. Along with other top officials, he needed guidance from the White House, which had not asked his department for a legal review of the order.

Halfway into the briefing, someone on the call looked up at a television in his office. “The president is signing the executive order that we’re discussing,” the official said, stunned. Continue reading
