Twitter’s new prototype application is rolling out to the first group of testers starting today, the company announced this afternoon by way of a tweet. The app, which Twitter is calling “twttr” as a throwback to its original name, was first introduced at the CES conference this January. It …

  ATT CEO Randall Stephenson said in December the company would soon adjust the content mix on its DirecTV Now streaming service and raise the monthly subscription to around the “$50 to $60” point — meaning, at least $10 per month more than it is today. This week, ATT is …

  The Opportunity rover has gone to a better place — Mars. Then about 15 years after reaching Mars, it shut down for good in the midst of a planet-wide dust storm. Before the plucky little rover passed on, it beamed back one final gift to the people of Earth: …

  People used to argue about whether or not planets like the eight (or more) in our solar system were rare. Starting in the 1990s with the discovery of the first exoplanets, it became clear planets are common around other stars. What about planets without stars? Astronomers have identified a …

  We know our Milky Way galaxy is big, but how big has been something of an open question. In the past, estimates of the total mass ranged from 500 billion to 3 trillion solar masses. It was difficult to pin down because of the unmeasurable dark matter making up …

  Satellites are physically quite secure orbiting the Earth, but the advent of cheaper high-power antennas makes them vulnerable in other ways. Engineers have only recently started taking cybersecurity seriously in satellite design, and as PCMag reports, that means hacking a satellite might not be as difficult as you think. …

  On March 7, 2009, the Kepler Space Telescope took off from Cape Canaveral aboard a Delta II rocket. For almost a decade, the space telescope expanded our understanding of the universe before it finally went dark for good last October. But it’s worth revisiting the spacecraft one last time, …

  Things have been going swimmingly for NASA’s InSight lander on the surface of Mars. After a textbook landing, InSight found itself in a nice, flat area perfect for deploying its seismic sensors. The weather monitoring package even allowed NASA to set up the first interplanetary weather report. It wouldn’t …

  It’s not a matter of if but when another giant asteroid or comet strikes the Earth. It’s happened all throughout history, and our mere presence on this planet won’t protect it. Although, we are the only species in the history of Earth with rockets and explosives (that we know …

  The dream of resurrecting species like the woolly mammoth via genetic engineering is old enough that I remember reading articles about it in school 30 years ago. We may never be able to recover enough pristine genetic material from an intact woolly mammoth to make that approach feasible, but …
