Astronomers find a famous exoplanet's doppelganger
One object has long been known: the 13-Jupiter-mass planet beta Pictoris b, one of the first planets discovered by direct imaging, back in 2009. The new object, dubbed 2MASS 0249 c, has the same mass, brightness, and spectrum as beta Pictoris b. (2018-07-16)

Light receptors determine the behavior of flashlight fish
Biologists at the Ruhr-Universität Bochum characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. As published on the July 11, 2018, in PLOS ONE the scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior. (2018-07-12)

The Gaia Sausage: The major collision that changed the Milky Way galaxy
An international team of astronomers has discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed the 'Sausage' galaxy. The cosmic crash was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy, fashioning both its inner bulge and its outer halo, the astronomers report in a series of new papers. (2018-07-04)

Theory of general relativity proven yet again in new research
In a novel test of Einstein's theory of general relativity, an international group of astronomers has demonstrated that the theory holds up, even for a massive three-star system. (2018-07-04)

Even phenomenally dense neutron stars fall like a feather
Harnessing the exquisite sensitivity of the National Science Foundation's Green Bank Telescope (GBT), astronomers have given one of Einstein's predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system -- two white dwarf stars and one ultra-dense neutron star -- the researchers determined that even phenomenally compact neutron stars 'fall' in the same manner as their less-dense counterparts, an aspect of nature called the 'Strong Equivalence Principle.' (2018-07-04)

Physicists come in 3 types, say mathematicians
As of 2013, there were 7.8 million researchers globally, according to UNESCO. This means that 0.1 percent of the people in the world professionally do science. Their work is largely financed by governments, yet public officials are not themselves researchers. To help governments make sense of the scientific community, Russian mathematicians have devised a researcher typology. The authors initially identified three clusters, which they tentatively labeled as ''leaders,'' ''successors,'' and ''toilers.'' (2018-06-28)

More clues that Earth-like exoplanets are indeed Earth-like
Researchers suggest that two Earth-like exoplanets (Kepler-186f and 62f) have very stable axial tilts, much like the Earth, making it likely that each has regular seasons and a stable climate. (2018-06-28)

Frankfurt physicists set limits on size of neutron stars
How large is a neutron star? Previous estimates varied from eight to sixteen kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 kilometres by using an elaborate statistical approach supported by data from the measurement of gravitational waves. The researchers' report appears in the current issue of Physical Review Letters. (2018-06-26)

(2018-06-20)

Hunting molecules to find new planets
It's impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers led by UNIGE have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet. (2018-06-18)

UNH researcher captures best ever evidence of rare black hole
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated. New research coming out of the Space Science Center at the University of New Hampshire shows the strongest evidence to date that this middle-of-the-road black hole exists, by serendipitously capturing one in action devouring an encountering star. (2018-06-18)

The chances of detecting clumps in atomic nuclei are growing
What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case of several light nuclei, experimental confirmation of the individualism or family nature of nucleons will now be simpler thanks to predictions presented by Polish physicists from Cracow and Kielce. (2018-06-14)

Distant moons may harbor life
Researchers at the University of California, Riverside and the University of Southern Queensland have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, in their atmospheres. (2018-06-14)

Astronomers see distant eruption as black hole destroys star
Scientists get first direct images showing fast-moving jet of particles ejected as a supermassive black hole at the core of a galaxy shreds a passing star. (2018-06-14)

Trio of infant planets discovered around newborn star
Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified three discrete disturbances in a young star's gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there. (2018-06-13)

Genetic soil prospecting yields wealth of potential antibiotics
Though soil bacteria have provided some of our best antibiotics, the drugs come from a small group of all the microbes in soil. UC Berkeley and Berkeley Lab scientists used metagenomics to sequence all the genomes of soil microbes in a teaspoon of soil to search for molecules that look like antibiotics. They found several hundred clusters of genes similar to the genes of known antibiotics, plus other complex and possibly useful molecules. (2018-06-13)

Research shows short gamma-ray bursts do follow binary neutron star mergers
