Signs of ground ice found on ancient protoplanet asteroid Vesta

Scientists have found evidence that there may be ground ice on Vesta, the brightest asteroid visible from Earth. It’s not the first time that ice has been detected on space rocks, and it adds credibility to the idea that asteroids may have brought water to Earth’s oceans. As asteroids crashed into Earth, the impact would have …

Weird white dwarf pulsar baffles boffins as its pulsating pattern changes over decades

Scientists trying to crack the mystery behind the fastest-pulsating white dwarf have found that its brightness levels change over a timescale of decades. AR Scorpii is a distant, peculiar binary star system located 380 light years away. It’s made of a collapsed white dwarf star circling its larger red dwarf companion. It was …

Cassini probe's death dive to send data at just 27 kilobits per second

Space is nasty and sending data across 83 light-minutes of it isn't easy, so the Cassini probe's death dive into the clouds of Saturn will be an instruments-only affair undocumented by photographs. Cassini has surveyed Saturn since 2004 but is out of fuel, so will be crashed into Saturn instead of leaving it an an orbit that …

Boffins find a new way to catch the 'tails' of quasars in massive galaxies

Physicists have managed to analyze the hidden "tails" swirling around quasars in supermassive black holes by using a combination of radio telescopes and the Gaia space observatory. A quasar is an active black hole, identified by plumes of matter shooting out from its center, and a shroud of gas and dust known as an accretion …

Astroboffins map 845 galaxies in glorious 3D, maybe dark matter too

A team led by Sydney University's Dr Caroline Foster has created three-dimensional images of 845 galaxies, claiming it is the biggest collection of of 3D galactic representations ever gathered. Created since 2013, when the Sydney Australian Astronomical Observatory Multi-object Integral Field Spectrograph (SAMI) saw first …

Boffins fear we might be running out of ideas

Innovation, fetishized by Silicon Valley companies and celebrated by business boosters, no longer provides the economic jolt it once did. In order to maintain Moore's Law – by which transistor density doubles every two years or so – it now takes 18 times as many scientists as it did in the 1970s. That means each researcher's …

Pains of giving birth to stars gives heft to elliptical galaxies

The rate of star formation might play a bigger role in affecting a galaxy's shape than previously thought, according to a recent study. Galaxies, a smattering of dust, gas and stars glued together by gravitational attraction, come in all sorts of shapes and sizes. Edwin Hubble's classic "tuning fork" diagram describes four …

Boffins: 68 exoplanets in prime locations to SPY on humanity on Earth

Scientists on Earth have found thousands of exoplanets – but which of those potential alien civilizations are in the best position to discover us? It’s a question that a team of physicists from Queen’s University Belfast, Northern Ireland, and the Max Planck Institute for Solar System Research, Germany have been grappling with …

How alien civilizations deal with climate is a measure of how smart they are. Just sayin'...

A team of scientists has proposed a new classification system that grades how advanced alien civilizations are by examining how an exoplanet uses energy. No concrete evidence of advanced life has been found beyond Earth, but that doesn't stop scientists entertaining the idea of extraterrestrial societies. The new system is a …

Close Encounters of the Kuiper Belt kind: New Horizons to come within just 3,500km of MU69

If we're not all too hungover when New Year's Day 2019 rolls around, NASA will hopefully have a fun set of photos to show us because on that day New Horizons probe has been told to go within just 3,500km of Kuiper Belt Object MU69. Having nominated MU69 as next on New Horizons' itinerary in 2015, it's already pointed the probe …

Violent moon mishap will tear Uranus a new ring or two

Four of the 27 moons orbiting Uranus are on a collision course and will smash into each other, creating new rings around the distant ice giant. The prediction [PDF], published by researchers at the University of Idaho and Wellesley College, came from a study into the unusual behavior of one of Uranus' smallest moons Cressida. …
