Espectrógrafo de alta precisión ayuda a confirmar descubrimiento planetario

NEID es un espectrógrafo de velocidad radial de alta precisión que está diseñado para medir el bamboleo extremadamente diminuto de las estrellas cercanas, utilizando el efecto de la velocidad radial. Este efecto resulta de la fuerza gravitacional mutua entre un planeta y su estrella…

High-Precision NEID Spectrograph Helps Confirm First Gaia Astrometric Planet Discovery

NEID (rhymes with fluid) is a high-precision radial-velocity spectrograph that is designed to measure the extremely minute wobble of nearby stars using the radial velocity effect. This effect results from the mutual gravitational force between a planet and its host star which causes the…

Hubble Goes Hunting for Small Main Belt Asteroids

Astronomers and volunteer citizen scientists used Hubble’s unique capabilities to identify a largely unseen population of very small asteroids. The treasure hunt required perusing 37,000 archived Hubble images spanning 19 years. The payoff? Finding 1,701 asteroid trails, with 1,031 of the asteroids previously uncatalogued. About 400 of these uncatalogued asteroids are smaller than 1 kilometer.

El Observatorio Rubin impulsará una nueva era en misiones espaciales sin salir de la tierra

El Observatorio Vera C. Rubin ayudará a los científicos a identificar objetivos intrigantes para dar prioridad a futuras misiones espaciales, mediante la detección de millones de nuevos objetos en el Sistema Solar y revelar, con el mayor detalle jamás visto, el contexto más amplio en el que existen.

Rubin Observatory will Inspire a New Era in Space Missions without Ever Leaving the Ground

Vera C. Rubin Observatory will help scientists identify intriguing targets to prioritize for future space missions by detecting millions of new Solar System objects, and by revealing — in more detail than we’ve ever seen — the broader context in which these objects exist.

Hubble Snapshot of ‘Molten Ring’ Galaxy Prompts New Research

In this image, a remote galaxy is greatly magnified and distorted by the effects of gravitationally warped space. After its public release, astronomers used the picture to measure the galaxy’s distance of 9.4 billion light-years. This places the galaxy at the peak epoch of star formation in cosmic evolution.

Hubble Finds First Evidence of Water Vapor at Jupiter’s Moon Ganymede

Located ½-billion miles from the Sun, the water ice on Ganymede’s surface is frozen solid in frigid temperatures as low as minus 300 degrees Fahrenheit. This makes the ice as hard as rock. Still, a rain of charged particles from the Sun is enough to turn the ice into water vapor at high noon on Ganymede. This is the first time such evidence has been found, courtesy of the Hubble Space Telescope’s spectroscopic observations of aurora on Ganymede spanning two decades. The auroras are used to trace the presence of oxygen, which then is linked to the presence of water molecules sputtering off the surface. Ganymede has a deep ocean located an estimated 100 miles below the surface.

After Election: Making the Endangered Species Act More Effective

Following the presidential election, a leading group of scientists are making the case that a “rule reversal” will not be sufficient to allow the Endangered Species Act to do its job of protecting species. Instead, they’re calling for deeper improvements to the rules the U.S. Fish & Wildlife Service and the National Marine Fisheries Service use to apply the law–aiming to make the Act more effective and to gain bipartisan and industry support in an era of accelerating climate change.
The team’s analysis and policy recommendations were published in the journal Science.

Hubble Observations Suggest a Missing Ingredient in Dark Matter Theories

Astronomers using Hubble and the VLT have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why they have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new findings indicate that small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.

Upcoming Trimble Lecture Highlights Hubble’s 30th with Jennifer Wiseman of NASA on April 29

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.
