A team of physicists based at a lab near Rome, Italy, are about to switch on an experiment that could fundamentally alter our understanding of the universe.
It's no secret that the Milky Way is big, but new research shows that it may be much bigger than we ever imagined.
The research, described May 7 in the journal "Astronomy & Astrophysics," indicates that our spiral galaxy's vast rotating disk of stars spans at least 170,000 light-years, and possibly up to 200,000 light-years.
Data is an increasingly pervasive force in American life, with the power to shape perception and policy. And so it makes a certain amount of sense that Rensselaer Polytechnic Institute recently adopted a new "data dexterity" requirement for its students, starting in fall 2019.
TROY, N.Y. (AP) — Rensselaer Polytechnic Institute will be requiring all of its students to be able to use diverse datasets to solve complex problems.
RPI says its "data dexterity" requirement will ensure that all students graduating for the school in Troy, New York are prepared for an increasingly data-driven world.
The closest galaxy to our own is the majestic Andromeda galaxy, a collection of a trillion stars located a “mere” 2 million light years away. New research suggests that, contrary to previous estimates, this galaxy isn’t much bigger than the Milky Way, and is practically our twin. This means our galaxy won’t be completely devoured when the two galaxies collide in five billion years.
Some 56 million years ago, carbon surged into Earth's atmosphere, raising temperatures by 5°C to 8°C and causing huge wildlife migrations—a scenario that might mirror the world's future, thanks to global warming. But what triggered this so-called Paleocene-Eocene thermal maximum (PETM) has remained a mystery.
A period of skyrocketing global temperatures started with a bang, new research suggests.
Too little is known about the newfound impact to guess its origin, size or effect on the global climate, said geochemist Morgan Schaller of Rensselaer Polytechnic Institute in Troy, N.Y. But it fits in with the long-standing and controversial proposal that a comet impact caused the PETM. “The timing is nothing short of remarkable,” said Schaller, who presented the discovery September 27 at the Geological Society of America’s annual meeting.
This universe of ours is pretty big, and it might be bigger than we think.
Heidi Newberg, astronomer and physicist at Rensselaer Polytechnic Institute, is studying the size of the galaxy.
Dr. Heidi Newberg has worked in many areas of astronomy over the course of her career. She did her Ph.D. with the Berkeley Automated Supernova Search, which measured the supernova rates as a function of supernova type in Virgo-distance galaxies; and the Supernova Cosmology Project (SCP), which is measured the cosmological parameters Omega and Lambda using the light curves of distant supernovae. She shared the Gruber Cosmology Prize for her work with SCP.
In a collaborative and multidisciplinary study, scientists develop methods to explore phosphorene and its properties. Phosphorene, discovered in 2014, is related to the two-dimensional graphene and has been established to have numerous photonic applications. The majority of these properties, however, is its capacity for anisotropic electron conduction. This means that its electron conduction property changes depending on the crystal orientation.
The starry disk that is our galaxy may extend at least 50 percent farther from its apparent edge than we thought. Instead of being flat, the Milky Way appears grooved like a vinyl record, upping its width to at least 150,000 light-years, researchers now say.
When you think of our Milky Way Galaxy, you might imagine a smooth disk with spiral arms embedded in it, like swirls in a peppermint. But a second look at observations from the Sloan Digital Sky Survey (SDSS) suggests that our galaxy’s disk is actually corrugated.
A ring-like filament of stars wrapping around the Milky Way may actually belong to the galaxy itself, rippling above and below the relatively flat galactic plane. If so, that would expand the size of the known galaxy by 50 percent and raise intriguing questions about what caused the waves of stars.
While other researchers abandoned gallium nitride and tried less persnickety materials, the Japanese researchers pressed on. “They felt like the oddballs, talking about something nobody else was working on, so they were really out on their own there,” said Christian Wetzel, a physicist at the Rensselaer Polytechnic Institute in Troy, N.Y. “It took some character to not do what others were doing but keep [going] despite all the frustration.”
Blue LEDs, in combination with red and green LEDs (which had been discovered previously), make it possible to produce white light. This kind of lighting is much more energy efficient and has a longer life span than conventional incandescent lights, said Christian Wetzel, a physicist at Rensselaer Polytechnic Institute in Troy, New York ... Car lighting is another application where LEDs are making inroads. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for nighttime use, Wetzel said.
According to new research from Oak Ridge National Laboratory and Rensselaer Polytechnic Institute, a hybrid material, called graphene oxide frameworks, or GOFs, could provide a big advantage over the inefficient desalination processes currently in use.
Water is trying to avoid being in contact with graphene, so you can design it in such a way that you’re forcing the water not to be close to one layer but also not to be close to the other,” Meunier said. “This effect creates channels, which direct water through the system very quickly.”"
A $50,000 micro-grant program sponsored by Phi Sigma Kappa fraternity that is intended to improve the quality of life in the Mount Ida neighborhood will be launched on Wednesday. The fraternity, whose members attend Rensselaer Polytechnic Institute will hand out grants of up to $1,000 to homeowners, landlords, nonprofit groups and business owners in the community. The fraternity will award 50 grants over a five-year period.
It's all about robotics today at RPI. Thirty eight High School teams are showing off their creations in the Tech Valley Regional Competition. It's the first time this regional event has been held in the Albany area. Photojournalist Rich Frederick takes a look.
More than 1,000 high school students, along with hundreds of teachers, college and professional mentors, parents, and 3,000 pounds of metal, gears, and electronics will converge at the East Campus Athletic Village at Rensselaer Polytechnic Institue in Troy, N.Y., for two days of compeition today and Saturday.
Area high school students will take robots this weekend to Troy, N.Y., and Youngwood.
While McKeesport Area students pack for Troy and the first of two FIRST (For Inspiration and Recognition of Science and Technology) regional tests, others are headed for competition at Westmoreland County Community College.
Part of The Best Of Our Knowledge's series on astrobiology, this piece visits the the sixth annual Exxon-Mobile Bernard Harris Summer Science Camp at Rensselaer. The story features commentary from physics professor Wayne Roberge.
