| 2 May 2016 : Astronomers Discover Three Potentially Habitable Earth-Sized Worlds Around A Dim Star 40 Light-years Away
An international team of astronomers, including UC San Diego’s Professor Adam Burgasser and graduate student Daniella Bardalez Gagliuffi, has reported in Nature the discovery of three Earth-sized planets orbiting near the “habitable zone” of an ultracool dwarf star named TRAPPIST-1, 40 light years in the direction of the constellation Aquarius. These are the first terrestrial planets to be discovered around such a tiny and dim star, and opens a new avenue in the search for life beyond Earth. The planets were found via the transit method, in which a planet passing between us and its host star blocks a small portion of the starlight, producing a subtle but periodic dimming pattern. Multiple transits for this star were detected with the TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, and their timings indicate the presence of three planets with orbit periods between 1.5 days and 73 days. These short orbits are likely to be in or around the habitable zone of the star, a zone in which liquid water could potentially exist on the planets’ surfaces. Evidence that this is the case will have to wait until the 2018 launch of the James Webb Space Telescope, which will have the capability of measuring the chemical composition of these planets’ atmospheres.

| 20 April 2016 : Alison Coil acts as scientific consultant for the play|
Constellations at The Old Globe Theater
Professor Alison Coil served as the scientific consultant for a play at the Old Globe, called Constellations. She also headed up a post-show Q+A with the audience on April 16th called “Subject Matters".
The play takes place in a multiverse, based on the many worlds interpretation of quantum mechanics, and the lead character is a female astrophysicist. The audience sees the same two people play out their relationship in different parallel universes in which they make different decisions.
Coil met with the director, Rick Seer, to discuss the science behind the play and talked about how to stage it and convey the multiverse idea to the audience. She met with the two actors to answer their questions about the science and the characters. She also advised the scenic designer to create a hexagonal set that referenced the male character, a beekeeper, and because of the hexagonal mirrors used at the Keck Telescopes. Read More

| 23 March 2016 : Quantum detectors search for signatures of Quantum Gravity
Detectors developed for UCSD’s POLARBEAR-2 and Simons Array experiments are featured in this article in the IEEE Spectrum magazine. These antennas were invented in the 1980s to solve important problems in microwave polarimetry and were later perfected for use in Cosmology experiments such as POLARBEAR-2 and the Simons Array by CASS Professor Gabriel Rebeiz. These novel sensors will be deployed in 2017 to search for primordial gravitational waves from the Inflationary cosmological epoch which, if convincingly detected, would provide the strongest evidence for quantum gravity — a goal long sought after by physicists.

| 28 October 2015 : The B-Mode Story You Haven't Heard
It's a tough time to be a B-mode.
B-modes rocketed to fame in March 2014, when a team of scientists working on an experiment called BICEP2 announced the first direct evidence for primordial gravitational waves rippling out from the earliest moments of the universe: a distinctive imprint in the cosmic microwave background (the light left over from the Big Bang) called "B-mode polarization," or B-modes for short. Polarization describes the way that light-waves are oriented, and B-mode waves are twisted into a swirling pattern. The detection of these swirls was a stunning confirmation of the theory of cosmic inflation. Suddenly, B-modes were electromagnetic celebrities. PBS story: Read More
