NASA Reveals Mesmerizing Panorama Of Northern Sky With ‘Sprawling Dark Nebula’

KEY POINTS

  • NASA has revealed a panoramic image of the Northern Sky taken by TESS
  • TESS is a survey satellite with a purpose to discover exoplanets
  • With its newly improved data collection and processing, TESS will be able to take more precise observations on its next mission

NASA’s Transiting Exoplanet Survey Satellite (TESS) has taken about 208 photos of the Northern Sky, resulting in a mesmerizing panorama. NASA’s satellite which launched back in 2018 has captured about 75% of the sky in its two-year survey.

TESS, a survey satellite, has successfully carried out its purpose to hunt and discover exoplanets well beyond our solar system. To date, it has discovered 74 exoplanets. Astronomers are currently going through an additional 1,200 candidates, where most still await confirmation. About 600 of these exoplanets are found in the Northern Sky.

The Northern mosaic only displays a portion of the data TESS has returned.

Federal Safe to Work legislation receives support from the Northern Virginia Technology Council

The measure was introduced earlier this year to offer business protection from potential COVID-19 litigation. Opposition groups feel as though the measure could limit responsibility as businesses reopen amid an ongoing pandemic.

As businesses begin to reopen, many companies are introducing measures to ensure public safety amid the pandemic, including limited indoor capacities, mandated mask guidelines, temperature checks, and more. At the same time, a number of employers have been sued by the families of employees who contracted the coronavirus. This risk of coronavirus-related litigation has spurred members of Congress to introduce legislation.

Sen. John Cornyn introduced the Safeguarding America’s Frontline Employees to Offer Work Opportunities Required to Kickstart the Economy (Safe to Work Act on July 27. On Thursday, the Northern Virginia Technology Council (NVTC), announced its support of the legislation, stating that the bill protects businesses from coronavirus-related litigation as companies reopen.

“Liability exposure protections are

Are China’s pollution remediation efforts making the planet warmer? China’s efforts to combat aerosol pollution resulted in warming throughout the northern latitudes — ScienceDaily

A 10-year effort by China to improve air quality and reduce pollution-related health risks has caused warming in areas across the northern hemisphere, according to new work published in Environmental Research Letters.

Aerosols are tiny particles that are spewed into the atmosphere by human activities, such as burning coal and wood, or by geological phenomena, like volcanos. Their negative effects on air quality can damage human health and agricultural productivity.

Similar to how the aerosols emitted in a volcanic eruption can cause global temperatures to drop, some aerosols from human activity also have a cooling effect on the climate. Unlike greenhouse gases, which induce global warming by trapping heat in the atmosphere, aerosol particles can cause sunlight to be reflected away from the planet either directly or by interacting with clouds.

“This means that some of the effects of global warming are being masked by aerosol pollution,” explained lead

Northern Lights Possible Over U.S. This Week As Strong Geomagnetic Storms Predicted, Say Scientists

Have you ever seen the Northern Lights? If you live in northern U.S. states near the Canadian border then the night skies could play host to the sky phenomenon—also called the aurora borealis—at around midnight local time on Monday and later in the week, too.

In the wake of the Sun “waking-up” there have been reports of strong displays of aurora in the night sky in recent weeks, but so far they’ve been confined to the Arctic Circle.

However, the latest predictions from the NOAA Space Weather Prediction Center (NOAA SWPC) suggest high activity is coming this week that could mean aurora borealis being visible as far south as Oregon.

Whether anyone sees them depends not only on “space weather,” but also on local weather since heavy cloud will preclude any sightings.

Coldest Northern Hemisphere temperature officially confirmed

Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere.


The measurement was first recorded by a University of Wisconsin-Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991. An AWS is a standalone instrument suite developed by UW-Madison Space Science and Engineering Center and AMRC scientists and engineers to collect numerous environmental parameters such as air temperature, pressure, humidity, wind direction and speed. The information is then relayed via satellite back to SSEC in near real time.

Over time, these data have come to provide a benchmark for

‘Northern lights’ seen at Rosetta’s famous comet for the first time

Comet Chury in all its glory

Auroras, better known to we earthlings as northern or southern lights, aren’t limited to just planets and moons. For the first time, scientists have identified the same phenomenon at a comet.

The discovery comes courtesy of the European Space Agency’s Rosetta mission, which famously landed on the comet 67P/Churyumov-Gerasimenko, also known as Comet Chury, back in 2014. 

On Earth, we get auroras when energetic particles from the solar wind interact with our planet’s magnetosphere. When researchers looked at Chury in the far ultraviolet range of the electromagnetic spectrum, they were able to pick up a similar effect from solar wind electrons striking the cloud of gas, or coma, around the comet’s rocky nucleus.

“The resulting glow is one of a kind,” says Marina Galand of Imperial

Hints of fresh ice in northern hemisphere

Scientists used data gathered by NASA’s Cassini spacecraft during 13 years of exploring the Saturn system to make detailed images of the icy moon—and to reveal geologic activity.


New composite images made from NASA’s Cassini spacecraft are the most detailed global infrared views ever produced of Saturn’s moon Enceladus. And data used to build those images provides strong evidence that the northern hemisphere of the moon has been resurfaced with ice from its interior.

Cassini’s Visible and Infrared Mapping Spectrometer (VIMS) collected light reflected off Saturn, its rings and its ten major icy moons—light that is visible to humans as well as infrared light. VIMS then separated the light into its various wavelengths, information that tells scientists more about the
