NASA’s Hubble Space Telescope discovers Black Hole in unexpected place

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Hubble Space Telescope has found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

As if black holes weren’t mysterious enough, astronomers using NASA’s Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

A Hubble Space Telescope image of the spiral galaxy NGC 3147 appears next to an artist's illustration of the supermassive black hole residing at the galaxy’s core. The Hubble image shows off the galaxy's sweeping spiral arms, full of young blue stars, pinkish nebulas, and dust in silhouette. (Hubble Image: NASA, ESA, S.

NASA’s Hubble Space Telescope captures celestial Fireworks

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA asks you to imagine slow-motion fireworks that started exploding 170 years ago and are still continuing. This type of firework is not launched into Earth’s atmosphere, but rather into space by a doomed super-massive star, called Eta Carinae, the largest member of a double-star system.

A new view from NASA’s Hubble Space Telescope, which includes ultraviolet light, shows the star’s hot, expanding gases glowing in red, white and blue. Eta Carinae resides 7,500 light-years away.

This Hubble Space Telescope image of the giant, petulant star Eta Carinae is yielding new surprises. Telescopes such as Hubble have monitored the super-massive star for more than two decades. The star, the largest member of a double-star system, has been prone to violent outbursts, including an episode in the 1840s during which ejected material formed the bipolar bubbles seen here.

Small Planet discovered by NASA’s Transiting Exoplanet Survey Satellite

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A world between the sizes of Mars and Earth orbiting a bright, cool, nearby star has been discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS). The planet, called L 98-59b, marks the tiniest discovered by TESS to date.

Two other worlds orbit the same star. While all three planets’ sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets — that is, planets beyond our solar system — that have the best potential for this kind of follow-up.

NASA studies Asia Mountains Water Cycle

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA says that for more than a billion people, Asia’s high mountain ranges, Himalaya, Karakoram, and Hindu Kush, are the names of their most reliable water source.

Snow and glaciers in these mountains contain the largest volume of freshwater outside of Earth’s polar ice sheets, leading hydrologists to nickname this region the Third Pole. One-seventh of the world’s population depends on rivers flowing from these mountains for water to drink and to irrigate crops.

NASA has New Technology set to Launch on SpaceX Falcon Heavy early Tuesday morning

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA reports that SpaceX is now targeting 1:30am CDT, Tuesday June 25th, 2019, for the Falcon Heavy launch of the Department of Defense Space Test Program-2 to allow time for additional ground system checkouts—vehicle and payload continue to look good.

NASA TV live launch coverage will start 30 minutes before launch, at 1:00am: www.nasa.gov/nasalive

The SpaceX Falcon Heavy rocket will launch from Cape Canaveral, Florida, carrying new NASA technology.

New technology from NASA's Jet Propulsion Laboratory will launch on the first night flight of the SpaceX Falcon Heavy on June 25th, 2019, from Cape Canaveral, Florida. The technology includes an atomic clock for self-driving spacecraft, climate-observing satellites and more. (SpaceX)

NASA’s Curiosity rover measures large amount of Methane on Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has discovered the largest amount of methane ever measured on Mars during the mission. Curiosity measured about 21 parts per billion units by volume (ppbv). One ppbv means that if you take a volume of air on Mars, one billionth of the volume of air is methane.

The finding came from the rover’s Sample Analysis at Mars (SAM) tunable laser spectrometer. It’s exciting because microbial life is an important source of methane on Earth, but methane can also be created through interactions between rocks and water.

This image was taken by the left Navcam on NASA's Curiosity Mars rover on June 18, 2019, the 2,440th Martian day, or sol, of the mission. It shows part of "Teal Ridge," which the rover has been studying within a region called the "clay-bearing unit." (NASA/JPL-Caltech)

NASA’s Operation IceBridge data shows Long-Term Sea Level Rise from Greenland Ice

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Using NASA data, a new modeling study of Greenland’s melting ice sheet reveals it could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate.

The study, which used data from NASA’s Operation IceBridge airborne campaign, was published in Science Advances today.

In the next 200 years, the ice sheet model shows that melting at the present rate could contribute 19 to 63 inches to global sea level rise, said the team led by scientists at the Geophysical Institute at the University of Alaska Fairbanks.

The Greenland Ice Sheet is the second-largest body of ice in the world, covering roughly 650,000 square miles of Greenland's surface. If it melts completely, it could contribute up to 23 feet of sea level rise, according to a new study using data from NASA's Operation IceBridge. (NASA / Jefferson Beck)

NASA’s twin E-TBEx CubeSats to study how signals get disrupted in Earth’s Ionosphere

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In June 2019, the NASA twin E-TBEx CubeSats — short for Enhanced Tandem Beacon Experiment — are scheduled to launch aboard the Department of Defense’s Space Test Program-2 launch.

The launch includes a total of 24 satellites from government and research institutions.

They will launch aboard a SpaceX Falcon Heavy from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

This visualization shows the relative density of certain particles in Earth's ionosphere. The E-TBEx CubeSats will explore how signals from satellites to Earth can be disrupted as they pass through this region. (NASA)

NASA’s Measure of Earth’s Temperature accuracy confirmed by new study

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A new assessment of NASA’s record of global temperatures revealed that the agency’s estimate of Earth’s long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values are likely accurate to within 0.09 degrees Fahrenheit (0.05 degrees Celsius) in recent decades, and 0.27 degrees Fahrenheit (0.15 degrees C) at the beginning of the nearly 140-year record.

Earth’s long-term warming trend can be seen in this visualization of NASA’s global temperature record, which shows how the planet’s temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average. (NASA’s Scientific Visualization Studio/Kathryn Mersmann)

NASA Scientist may have discovered way to detect Life Friendly Climates on Other Worlds

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA says scientists may have found a way to tell if alien worlds have a climate that is suitable for life by analyzing the light from these worlds for special signatures that are characteristic of a life-friendly environment.

This technique could reveal the inner edge of a star’s habitable zone, the region around a star where liquid water could exist on the surface of a rocky planet.

“Habitable planets by definition have water on their surfaces,” said Eric Wolf of the University of Colorado, Boulder. “However, water can come in the forms of ocean, ice, snow, vapor, or cloud. Each of these forms of water have very different effects on climate. ”
