How long is a day on Venus? Scientists crack mysteries of our closest neighbor

Fundamentals such as how many hours are in a Venusian day provide critical data for understanding the divergent histories of Venus and Earth, UCLA researchers say. Credit: NASA/JPL-Caltech

Venus is an enigma. It’s the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.

Now, new observations from the safety of Earth are lifting the veil on some of Venus’ most basic properties. By repeatedly bouncing radar off the planet’s surface over the last 15 years, a UCLA-led team has pinned down the precise length of a day on Venus, the tilt of its axis and the size of its core. The findings are published today in the journal Nature Astronomy.

New astronomical survey utilizes the Green Bank Telescope to give clearest view of ionized gas in the Milky Way

The Green Bank Telescope with a dark sky of stars.

Astronomical surveys mapping regions of the Galaxy have been collected and studied for decades. These surveys allow researchers to compare previous data, further characterize objects or images of the sky, and learn more through statistical analysis.  For the National Science Foundation’s Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS), researchers took advantage of the power of the GBT, located in Pocahontas County, West Virginia, to better understand the impact of massive stars in the Milky Way.

West Virginia Students Contact International Space Station LIVE

How would you feel if you could talk to an astronaut, orbiting over 200-miles above you in space?

Friday, May 7th at 8:00 AM EDT, students in rural West Virginia will experience this once in a lifetime opportunity. Green Bank Elementary-Middle School (GBEMS) will be contacting astronaut Mark Vande Hei on the International Space Station (ISS).

Can Green Bank Telescope Defend Against Asteroid Apophis?

The National Science Foundation’s Green Bank Telescope (GBT) is teaming up with NASA’s Goldstone Deep Space Communications Complex (GDSCC) to observe this potentially hazardous asteroid. These new observations of Apophis will allow scientists to improve their understanding of the asteroid’s orbit, and better estimate the odds that Apophis could strike the Earth in the future. Predicting if there is a real chance of impact, decades ahead of time, gives scientists the opportunity to take action to manipulate the orbit of Apophis to avoid a collision in the future.

This “waterfall image” is actually three separate observations combined to show NASA’s Mars Perseverance rover as it enters the Martian atmosphere before touching down on the red planet. Green Bank Observatory Data Analyst Amber Bonsall created this image using data received by the Green Bank Telescope (GBT). The GBT was pointed at Mars to observe communications from the rover as it landed February 18th, 2021 at 3:55 p.m. EDT.

West Virginia’s Role in the NASA Perseverance Mars Rover Landing

The National Science Foundation’s Green Bank Telescope (GBT), located in Green Bank, West Virginia, plays a role in the upcoming mission of the NASA’s Mars 2020 Perseverance rover. The GBT will receive communications from the rover as it arrives on Mars on February 18th and pass these on to NASA’s Jet Propulsion Laboratory (JPL) located in southern California.

Qorvo, NRAO, and Green Bank Observatory Develop New Tech for Identifying Threats from Near-Earth Objects

Qorvo® (Nasdaq: QRVO), a leading provider of innovative radio frequency (RF) solutions that connect the world, today announced its Spatium® solid-state power amplifier (SSPA) technology will play a key role in a new planetary radar experiment using the National Science Foundation’s Green Bank Telescope (GBT). Planetary radar is instrumental in characterizing Near-Earth Objects (NEOs) by providing precision measurement of shape, rotation, position, and an estimate of composition.

Looking up at the night’s sky, twinkling with celestial objects, do you ever dream of discovering something new? How about something that sheds light on the early days of the Universe? A decade ago, citizen scientists, in the Galaxy Zoo project, helped astronomers discover a new and important class of galaxies, the Green Peas.
