A team of astronomers, including two from MIT, has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar, the light of which was emitted just 690 million years after the Big Bang. That light has taken about 13 billion years to reach us — a span of time that is nearly equal to the age of the universe._MIT

On Aug. 17, the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the fifth fingerprint of a massive disturbance in spacetime since LIGO began operations in September 2015. Unlike the first four sets of ripples, which reflected collisions between two black holes, the shape of these spacetime distortions suggested a collision between two neutron stars. _Princeton University
Looking at massive galaxy clusters, EPFL astronomers have observed that their brightest galaxies within them “wobble” — an unexpected phenomenon in current models. The discovery, published in MNRAS, adds to the body of evidence of dark matter beyond the Standard Cosmological Model (ΛCDM). _EPFL
Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds, say scientists at McMaster University and the Max Planck Institute in Germany.
Their calculations suggest that wet and dry cycles bonded basic molecular building blocks in the ponds’ nutrient-rich broth into self-replicating RNA molecules that constituted the first genetic code for life on the planet.
New work from a research team including the director of Carnegie’s Las Campanas Observatory, Leopoldo Infante, has tripled the sample size of known galaxies that can teach scientists about a key period in the universe’s history, when the lights came back on after the so-called dark ages.
NASA’s Hubble Space Telescope team has unveiled a new e-book titled “Hubble Focus: Our Amazing Solar System.” It kicks off a series of e-books that will showcase the telescope’s recent contributions to many different fields of astronomy.
In a new paper published in Science, researchers at the University of Pennsylvania provided a detailed look into how self-assembled squid lenses have evolved to adjust for light distortion, which allows them to see clearly in the dim waters of the open ocean. _Penn News
One hundred years after Albert Einstein predicted the existence of gravitational waves, scientists have finally spotted these elusive ripples in space-time. In a highly anticipated announcement, physicists with the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) revealed on 11 February that their twin detectors have heard the gravitational ‘ringing’ produced by the collision of two black holes about 400 megaparsecs (1.3 billion light-years) from Earth._nature

Astronomers have announced evidence for a new ninth planet in the solar system: a giant nearly the size of Neptune that takes 15,000 years to orbit the sun. _Science AAAS
Astronomers have used the NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope to study the atmospheres of ten hot, Jupiter-sized exoplanets in detail, the largest number of such planets ever studied. The team was able to discover why some of these worlds seem to have less water than expected – a long-standing mystery._ESA
ESO’s VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared._ESO
Scientific Article: We construct a 3D map of the spatial density of OB stars within 500 pc from the Sun using the Hipparcos catalogue and find three large-scale stream-like structures that allow a new view on the solar neighbourhood. The spatial coherence of these blue streams and the monotonic age sequence over hundreds of parsecs suggest that they are made of young stars, similar to the young streams that are conspicuous in nearby spiral galaxies._ Astronomy & Astrophysics
Solar physicists have captured the first direct observational signatures of resonant absorption, thought to play an important role in solving the “coronal heating problem” which has defied explanation for over 70 years._NAOJ
A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15, and 24 days. The paper is being published in the Astrophysical Journal.
