    The Arecibo Observatory will remain open, NSF says

    The iconic Arecibo Observatory has survived a hurricane and dodged deep budget cuts. On November 16, the National Science Foundation, which funds the bulk of the observatory’s operating costs, announced that they would continue funding the radio telescope at a reduced level.

    It’s not clear yet who will manage the observatory in the long run, or where the rest of the funding will come...

    Colliding black holes are reported for a fifth time

    Spacetime ripples from black holes are becoming routine.

    For a fifth time, scientists have reported the detection of two colliding black holes via their gravitational waves, tiny vibrations that warp the fabric of spacetime. Unlike previous gravitational wave detections, which were heralded with news conferences often featuring panels of scientists squinting at journalists under bright...

    In science, some big risks are worth the rewards

    At the end of my previous Editor’s Note (SN: 11/11/17, p. 2), I wrote about one of the great discoveries of the 1920s. By studying distant nebulae, Edwin Hubble found that our galaxy is not alone in the universe. Instead, it is one of an amazing multitude of “island universes.” When I wrote those words, I had no idea that just a couple of weeks later, I would get to visit the impressive...

    Haze keeps Pluto cool by kicking heat out to space

    Blame Pluto’s haze for the dwarf planet’s unexpected chilliness. Clusters of hydrocarbons in the atmosphere radiate heat back into space, keeping the dwarf planet cool, a new study suggests. Pluto may be the only world in the solar system whose atmospheric temperature is controlled by solid particles, rather than gas, researchers report in the Nov. 16 Nature.

    Most planets’ temperatures...

    New camera on Palomar telescope will seek out supernovas, asteroids and more

    A new eye on the variable sky just opened. The Zwicky Transient Facility, a robotic camera designed to rapidly scan the sky nightly for objects that move, flash or explode, took its first image on November 1.

    The camera, mounted on a telescope at Caltech’s Palomar Observatory near San Diego, succeeds the Palomar Transient Factory. Between 2009 and 2017, the Palomar Transient Factory...

    Ancient spiral galaxy is 11 billion years old

    Astronomers have spotted a spiral galaxy more ancient than any seen before.

    The galaxy, called A1689B11, emitted its light 11 billion years ago, just 2.6 billion years after the Big Bang. Researchers had previously reported a spiral galaxy that dates to 10.7 billion years ago.

     Astronomer Tiantian Yuan at Swinburne University of Technology in Melbourne, Australia and colleagues...

    This star cheated death, exploding again and again

    A shocking supernova refuses to die.

    This exploding star, named iPTF14hls, has erupted continuously for the last three years, and it may have had two other outbursts in the past, astronomers report in the Nov. 9 Nature. Such a tireless supernova could be the first example of a proposed explosion that involves burning antimatter in a stellar core — or it could be something new altogether...

    NASA wants your help naming New Horizons’ next destination

    NASA’s New Horizons mission needs a catchier nickname for its next destination. The bar isn’t exactly high.

    On New Year’s Day 2019, the spacecraft will fly by the tiny Kuiper Belt world that bears the official designation of (486958) 2014 MU69. NASA announced Monday that it is asking the public for an easier-to-remember nickname. The SETI Institute is hosting the contest.

    As with...

    A sandy core may have kept Enceladus’ ocean warm

    A soft heart keeps Enceladus warm from the inside. Friction within its porous core could help Saturn’s icy moon maintain a liquid ocean for billions of years and explain why it sprays plumes from its south pole, astronomers report November 6 in Nature Astronomy.

    Observations in 2015 showed that Enceladus’ icy surface is a shell that’s completely detached from its rocky core, meaning the...

    See a new mosaic of images of comet 67P from the Rosetta mission

    A year after the Rosetta spacecraft’s rendezvous with comet 67P/Churyumov-Gerasimenko came to an end, the views are still stunning. This montage, released in September by the European Space Agency, includes 210 of the thousands of images taken by Rosetta and the Philae lander and recaps the daring mission to explore the space rock. The images are arranged chronologically (starting at the top...
