Lunacy: how science fiction is powering the new moon rush

Posted by in categories: futurism, space

Science fiction is often seen as an anticipation – a fiction peculiarly expected to graduate into fact. But if technologies once found only in SF do sometimes become real they do not, in so doing, always cease to be science fictional. SF is not, after all, simply a literature about the future; it is a literature about the shock of new capacities and new perspectives, about transcendence, estrangement and resistance in the face of the inhuman. Its ideas shape and constrain the ways in which technological possibilities are seen, understood and experienced long after those possibilities are first tentatively realised. It illuminates the dreams of Musk, Bezos and all the other new moon-rushers.


Fifty years after the first moon landings, a new generation of space travellers, from Xi Jinping’s taikonauts to Jeff Bezos, are racing to colonise our nearest neighbour. Is reality catching up with sci-fi?

Eighteen Earth-sized exoplanets discovered

Posted by in category: space

Scientists at the Max Planck Institute for Solar System Research (MPS), the Georg August University of Göttingen, and the Sonneberg Observatory have discovered 18 Earth-sized planets beyond the solar system. The worlds are so small that previous surveys had overlooked them. One of them is one of the smallest known so far; another one could offer conditions friendly to life. The researchers re-analyzed a part of the data from NASA’s Kepler Space Telescope with a new and more sensitive method that they developed. The team estimates that their new method has the potential of finding more than 100 additional exoplanets in the Kepler mission’s entire data set. The scientists describe their results in the journal Astronomy & Astrophysics.

Somewhat more than 4000 planets orbiting stars outside our solar system are known so far. Of these so-called exoplanets, about 96 percent are significantly larger than our Earth, most of them more comparable with the dimensions of the gas giants Neptune or Jupiter. This percentage likely does not reflect the real conditions in space, however, since small planets are much harder to track down than big ones. Moreover, small worlds are fascinating targets in the search for Earth-like, potentially habitable planets outside the solar system.

The 18 newly discovered worlds fall into the category of Earth-sized planets. The smallest of them is only 69 percent of the size of the Earth; the largest is barely more than twice the Earth’s radius. And they have another thing in common: all 18 planets could not be detected in the data from the Kepler Space Telescope so far. Common search algorithms were not sensitive enough.

Chandra Discovers New Signal for Neutron Star Collision

Posted by in category: space

  • A neutron star merger without an observed gamma-ray burst has been discovered using NASA’s Chandra X-ray Observatory.
  • This result gives astronomers another way to track down neutron star mergers as well new information about their interiors.
  • This source, called XT2, is located in the Chandra Deep Field-South, the deepest X-ray image ever obtained.
  • By studying how XT2 changed in X-ray brightness, astronomers were able to identify it as two neutron stars that merged into a larger one.

These images show the location of an event, discovered by NASA’s Chandra X-ray Observatory, that likely signals the merger of two neutron stars. A bright burst of X-rays in this source, dubbed XT2, could give astronomers fresh insight into how neutron stars — dense stellar objects packed mainly with neutrons — are built.

XT2 is located in a galaxy about 6.6 billion light years from Earth. The source is located in the Chandra Deep Field South (CDF-S), a small patch of sky in the Fornax constellation. The CDF-S is the deepest X-ray image ever taken, containing almost 12 weeks of Chandra observing time. The wider field of view shows an optical image from the Hubble Space Telescope of a portion of the CDF-S field, while the inset shows a Chandra image focusing only on XT2. The location of XT2, which was not detected in optical images, is shown by the rectangle, and its host galaxy is the small, oval-shaped object located slightly to the upper left.

Evolutionary Biologist: Mars Colonists Will Mutate Really Fast

Posted by in categories: biotech/medical, space

Contact with Earthlings could even be deadly for Martians — and vice versa. Mars doesn’t have any microorganisms to carry disease, and so if cross contamination between Earth and Mars is controlled, Solomon explains that all infectious disease could be eliminated — meaning there should be no intimate connection between the two groups.

But all mutation isn’t bad. Every new baby on Earth is born with 60 new mutations, a number which Solomon says will jump to the thousands on Mars. By mutating, humans on Mars would gain critical, life-saving benefits to cope with the brutal planet: a different skin tone to protect from radiation, less reliance on oxygen to adapt to the thin atmosphere, denser bones to counteract calcium loss during pregnancy.

Solomon even suggests that we could use CRISPR to more purposefully design these helpful mutations.

Geologists Just Discovered a Source of Volcanoes Deeper Than Ever Before

Posted by in categories: materials, space

Researchers have pinpointed a previously unknown source of volcanoes in the extreme depths of Earth — in the transition zone between the upper and lower mantle.

Until now, we thought we had a handle on the ways in which volcanoes form, welling up from the molten regions in the upper mantle beneath our planet’s crust, but the new discovery takes things much farther down.

In the Bermuda islands, which sit atop an extinct volcanic seamount, geologists have found the first direct evidence that material from the transition zone, between 400 and 650 kilometres (250 and 400 miles) below Earth’s surface, can bubble up and be spewed out of volcanoes.
