Artificial kidneys, gay-straight alliances and junkyard batteries captured readers' attention in 2016. Read More

Jedidah Isler, a National Science Foundation postdoctoral fellow in Vanderbilt’s Department of Physics and Astronomy, has emerged as an increasingly high-profile advocate for diversity among science, technology, engineering and mathematics researchers. Read More

The results of a new study make it far less likely that KIC 8462852, popularly known as Tabby’s star, is the home of industrious aliens who are gradually enclosing it in a vast shell called a Dyson sphere, a theory that went viral over the past year. Read More

A new generation of gamma-ray spectrometer being developed by researchers and students in the Fisk-Vanderbilt Master's-to-Ph.D. Bridge program is perfectly suited for detecting valuable minerals hidden within the asteroids, comets, moons and minor planets in the solar system. Read More

A Vanderbilt team of scientists have developed a new formulation for cosmic viscosity which strongly favors the "Big Rip" end of the universe. Read More

Explainer: the mysterious dark energy that speeds the universe’s rate of expansion Read More

Bob O'Dell reflects on the challenges of building the Hubble Space Telescope, launched 25 years ago. Read More

"No matter which (a)theistic background informs your theology, you may have to wrestle with the data astronomers will be bringing to houses of worship in the very near future," writes astronomy professor David Weintraub for The Conversation. Read More

In the latest VUCast: A Vanderbilt astronomer looks at how different religions may handle alien life; why early Earth may not have been as “hellish” as first thought; and check out the national baseball championship bling! Watch now. Read More

Researchers have developed a model that estimates the effect that a star's diet has on its chemical composition. This model will add substantially to astronomers’ understanding of the process of planet formation as well as assist in the ongoing search for Earth-like exoplanets. Read More

Vanderbilt astronomers have developed a model that predicts the effect that ingesting earth-like planets has on the chemical composition of stars like the Sun -- a capability that can aid in efforts to find Earth-like exoplanets. Read More

In the latest VUCast: What people with autism see may not match what they hear; how “supersizing” could help you lose weight; and hear what earned a Vanderbilt astronomer a Grammy nomination. Watch now. Read More

Two Vanderbilt astronomers are among an international team that has discovered a surprising new class of “hypervelocity stars” – solitary stars moving fast enough to escape the gravitational grasp of the Milky Way galaxy. Read More

A NASA astrophysicist and Vanderbilt graduate student Lisa Upton have confirmed the existence of giant convection cells flowing slowly on the sun, lending further insight into the transport of heat from its core and the origin of cycles of sunspot activity that affect essential satellite-based communications such as cell phones and TV broadcasting. Read More

Science has progressed from wild speculation about Earth’s planetary neighbors—including how they formed and whether they are inhabited—to a better understanding of our celestial neighborhood, David Weintraub, professor of astronomy, writes in "Scientific American." Read More

Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity on its surface. Read More

Fisk and Vanderbilt's Bridge Program mentors talented minority students pursuing advanced science degrees. Keivan Stassun, professor of astronomy and director of the Fisk-Vanderbilt Masters-to-Ph.D. Bridge Program, is quoted. Read More

The reason dark matter, which makes up 85 percent of all the matter in the universe, is invisible could be because it possesses a rare, donut-shaped type of electromagnetism instead of the more exotic forces that have been proposed, according to an analysis of a pair of Vanderbilt theoretical physicists.

A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light years away. The discovery was made using inexpensive ground-based telescopes, including one specially designed to detect exoplanets and jointly operated by astronomers at Ohio State University and Vanderbilt University.

A team of researchers, headed by Vanderbilt astronomer C. Robert O’Dell, has combined images from NASA’s Hubble Space Telescope with images from ground-based telescopes to reconstruct the three-dimensional shape of the iconic nebula with unprecedented precision. In the process, they determined that it is considerably different than previously thought. Read More
