NASA shares 'spectacular" image of the southern lights from International Space Station
Thursday, 25 August 2022 15:35
Is NASA campaigning to have the galaxy's best Instagram page? It sure seems that way with the latest images from the James Webb Space Telescope of Jupiter and last month's stunning shots of the Carina Nebula and Southern Ring Nebula.
And now, the space agency is sharing a remarkable image of the southern lights, or aurora australis, taken from the International Space Station.
The southern lights, which are similar to the aurora borealis, can be seen best from Tasmania, New Zealand and Antarctica, according to Smithsonian Magazine.
Webb detects carbon dioxide in exoplanet atmosphere
Thursday, 25 August 2022 13:00
The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away. The result provides important insights into the composition and formation of the planet, and is indicative of Webb’s ability to also detect and measure carbon dioxide in the thinner atmospheres of smaller rocky planets.

NASA engineer develops tiny, high-powered laser to find water on the moon
Thursday, 25 August 2022 12:08
Finding water on the moon could be easier with a Goddard technology that uses an effect called quantum tunneling to generate a high-powered terahertz laser, filling a gap in existing laser technology.
Locating water and other resources is a NASA priority crucial to exploring Earth's natural satellite and other objects in the solar system and beyond. Previous experiments inferred, then confirmed the existence of small amounts of water across the moon. However, most technologies do not distinguish among water, free hydrogen ions, and hydroxyl, as the broadband detectors used cannot distinguish between the different volatiles.
ESA ready for “historic” Artemis 1 mission

A NASA astronaut flying to the International Space Station on a Soyuz spacecraft next month says his training hasn’t been affected by tensions with Russia or uncertainty about the status of his mission.
Scientists take another theoretical step to uncovering the mystery of dark matter, black holes
Thursday, 25 August 2022 10:01
Much of the matter in the universe remains unknown and undefined, yet theoretical physicists continue to gain clues to the properties of dark matter and black holes. A study by a team of scientists including three from Stony Brook University proposes a novel method to search for new particles not currently contained in the standard model of particle physics. Their method, published in Nature Com How scientist established a two-stage solar flare early warning system?
Thursday, 25 August 2022 10:01
Solar flares are solar storm events driven by the magnetic field in the solar activity area. When the flare radiation comes to the Earth's vicinity, the photo-ionization increases the electron density in the D-layer of the ionosphere, causing absorption of high-frequency radio communication, scintillation of satellite communication, and enhanced background noise interference with radar. Statisti Uranus to begin reversing path across the night sky on Wednesday
Thursday, 25 August 2022 10:01
As part of a cosmic phenomenon called retrograde motion, Uranus - the second-to-last planet in our solar system - will reverse its eastward course on Wednesday and begin moving west in the sky for a few months.
Retrograde motion occurs as the Earth moves around the sun and the stellar views at night change little by little. The orbit, in turn, makes objects like planets in our solar s Curiosity Versus the Sand Again: Sols 3566-3567
Thursday, 25 August 2022 10:01
The "road" through Paraitepuy pass continues to challenge our intrepid Curiosity rover. We attempted to cross another large sand ripple (formally called a transverse aeolian ridge, or TAR) in Tuesday's plan.
However, we found out this morning that Curiosity had automatically stopped the drive when the rover's wheels slipped more than expected right before they reached the crest of the TAR. Sol 3565: Over, Around, and Through
Thursday, 25 August 2022 10:01
We filled much of today's plan imaging the wonders around and ahead of us as we pick our way through "Paraitepuy Pass" - the towering buttes, geologic relationships, and layers that have drawn our attention for a literal decade.
But it is also fun to look back on how we got to where we are. The image above traces a small segment of our path traversing the obstacles that guard the pass - ov Slow and steady does it on Sol 3564
Thursday, 25 August 2022 10:01
We are making slow but steady progress through the "Paraitepuy pass," having passed the approximate halfway point over the weekend. Today's one sol plan found us staring around the corner at the neck of the pass and considering our drive path forward.
Sometimes, our drive forward is smooth and flat ... neither word can be used here! Our drive forward has abundant sand and sharp rocks, so f Scientists say exoplanet 100 light years from Earth may be covered with deep ocean
Thursday, 25 August 2022 10:01
A team of researchers have discovered an exoplanet about 100 light years away from Earth in the Draco constellation, and they say the world appears to be covered in a deep ocean.
The exoplanet - called TOI-1452b - is slightly larger than the Earth and is located in a "Goldilocks zone," where temperatures are neither too hot nor too cold for liquid water to exist. Therefore, astronomer
