A pair of binary neutron stars in the Milky Way galaxy – discovered eight years ago by a pulsar survey developed at Cornell University – is giving researchers a front-row seat at what they believe will be the stars’ eventual cataclysmic merger.

Using a new technique originally designed to explore the cosmos, scientists have unveiled structures deep inside the Earth, paving the way towards a new map revealing what Earth’s interior looks like.
Read moreScientists from the University of New Hampshire’s Space Science Center will use a $4.6 million grant from NASA to create the Student Collaboration Project that will offer a diverse group of college students from across the country hands-on research experience designing and building small satellites that will be launched into outer space and collect data for one of NASA’s space missions.

The American Institute of Physics, celebrating the 30th anniversary of the launch of the NASA/ESA Hubble Space Telescope, is delighted to host a virtual presentation by Stanford University’s Elizabeth Kessler in an upcoming Lyne Starling Trimble Science Heritage Public Lecture. The lecture series is presented by AIP and features science historians and writers who study the role of science and technology in modern society and culture. “Hubble Space Telescope Images and the Astronomical Sublime” will be hosted virtually, Thursday, May 7 at 3:30 p.m. Eastern (U.S.).

The American Institute of Physics is delighted to host a virtual lecture by Hubble Space Telescope senior project scientist Jennifer Wiseman in an upcoming Lyne Starling Trimble Science Heritage public lecture to celebrate Hubble’s 30th anniversary. The lecture series is hosted by AIP and highlights experts who study the role of science and technology throughout human history and modern society. “The Hubble Space Telescope: 30 Years of Discovery and Awe” will be hosted virtually, April 29 at 3:30 p.m. EDT.
Read moreA galactic visitor entered our solar system last year – interstellar comet 2I/Borisov. When astronomers pointed the Atacama Large Millimeter/submillimeter Array (ALMA) toward the comet on 15 and 16 December 2019, for the first time they directly observed the chemicals stored inside an object from a planetary system other than our own. This research is published online on 20 April 2020 in the journal Nature Astronomy.

When the sun expels plasma, the solar wind cools as it expands through space — but not as much as the laws of physics would predict. UW–Madison physicists now know the reason.

Peering into the darkness to see what we could not previously see, the Hubble Space Telescope has been delighting scientists and the general public with revealing details and images of galaxies and celestial phenomena. The American Institute of Physics recognizes and celebrates the momentous occasion of the 30th anniversary of its launch and Physics Today is highlighting the anniversary in its April issue with a look back at the history of the telescope and analysis of Hubble’s discoveries over the past 30 years.
Read more– Cornell University astronomers have created five models representing key points from our planet’s evolution, like chemical snapshots through Earth’s own geologic epochs. The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for Earth-like planets in distant solar systems.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.
