Coast-to-coast auroras possible in the US tonight as Earth clashes with a 'coronal hole' on the sun
- Coast-to-coast auroras could be visible in the US tonight due to a 'coronal hole' on the sun.
- The National Oceanic and Atmospheric Administration (NOAA) issued a G2 geomagnetic storm watch, predicting minor technological disruptions and increased chances of seeing auroras at low latitudes.
- Coronal holes are cooler, darker regions in the sun's corona that allow high-speed solar winds to escape and stream towards Earth.
- The best chances of spotting an aurora are on dark, clear nights between 10pm and 2am, away from artificial lights.

Longest molecules ever found on Mars may be remnants of building blocks of life
- NASA's Curiosity rover found the longest molecules ever on Mars, suggesting evidence for ancient life on the planet.
- Long carbon chains detected in a 3.7 billion-year-old rock sample from Yellowknife Bay could be remnants of fatty acids.
- Presence of these molecules hints at potential biological activity on Mars billions of years ago.
- The chains of hydrocarbons including decane, undecane, and dodecane were discovered using Curiosity's SAM instrument.
- Curiosity rover has explored areas like Yellowknife Bay and Mount Sharp on Mars since its arrival in 2012.
- The discovery of the hydrocarbon strings was accidental while searching for amino acids in a clay-rich sample named Cumberland.
- Researchers believe the fatty molecules may have originated from longer tails of fatty acids present in the Martian soil.
- Tests in the lab showed that undecanoic acid could break down into decane, supporting the theory of fatty acid origins.
- The detection of these carbon chains confirms Curiosity's ability to detect complex organic molecules on Mars.
- Researchers aim to bring Martian soil samples back to Earth for further analysis to understand the history of life on Mars.

- The new electrochemical approach achieves oxygen yields of up to 98.6%, surpassing natural photosynthesis and offering versatile applications from Mars to industrial settings.
- Testing the device with varying CO₂ levels, including simulated industrial exhaust and Mars air, proved its potential for producing oxygen efficiently.
- By integrating into industrial systems, the method could aid in reducing emissions, improving air quality, and supporting global climate goals.
- Generating solid carbon as a byproduct enhances environmental sustainability and offers possibilities for carbon storage and reuse.
- This innovation provides a practical method to fight climate change, produce oxygen on Mars, support underwater life, and enhance air purification systems.
- The new technology's scalability and efficiency hold promise for transforming harmful emissions into breathable air, benefiting humanity on Earth and beyond.
- Understanding the evolution and process of photosynthesis highlights its role in sustaining life on Earth, shaping ecosystems, and providing oxygen essential for survival.

James Webb telescope reveals 'cosmic tornado' in best detail ever — and finds part of it is not what it seems
- NASA's James Webb Space Telescope (JWST) has captured a stunning image of a 'cosmic tornado' known as Herbig-Haro 49/50 in the constellation Chamaeleon.
- Herbig-Haro objects are formed when ionized gas jets from newborn stars collide with surrounding interstellar material, creating bright and nebula-like structures.
- Herbig-Haro 49/50 was first discovered by NASA's Spitzer Space Telescope in 2006 and is located in the Chamaeleon I Cloud complex, about 625 light-years from Earth.
- The JWST image also revealed that a fuzzy object at the top of the gas pillar is actually a distant spiral galaxy in the background, not a part of Herbig-Haro 49/50.

Elusive 'Blaze Star' nova could finally appear in our skies this week after multiple false alarms
- T Coronae Borealis (T CrB), also known as the 'Blaze Star,' is a recurrent nova expected to appear in the night sky this week, triggered by an eruption in its binary star system.
- This spectacle, last seen in 1946, is challenging to predict accurately despite historical data indicating its recurrence every 80 years.
- The binary system includes a red giant and a white dwarf, with the latter undergoing explosive episodes when excess hydrogen accumulates on its surface.
- Multiple false alarms have been raised regarding the Blaze Star's appearance, with recent expectations pinpointing March 27 for its potential reemergence.
- A study suggests a pattern based on the orbital period between the stars could aid predictions, with potential future dates for the nova's appearance in subsequent years.
- The exact cause behind the recurrent nova's eruptions remains unclear, with empirical extrapolations guiding current predictions.
- Once visible, the Blaze Star will shine brightly in the Corona Borealis constellation and will be among the brightest objects in the night sky.
- Stargazers can use nearby constellations like Hercules and Boötes as guides to locate the nova, projected to have an apparent magnitude similar to the North Star.
- Enthusiasts equipped with telescopes or binoculars may enjoy observing the Blaze Star for several days after its initial visibility to the naked eye.
- Although the precise timing of the Blaze Star's appearance remains uncertain, its anticipated reemergence offers a fascinating celestial event for skywatchers.

'Very rare' black hole energy jet discovered tearing through a spiral galaxy shaped like our own
- A massive spiral galaxy, J2345-0449, located nearly a billion light-years away, has been discovered emitting powerful radio jets from its supermassive black hole.
- These strong radio jets, stretching over 5 million light-years, are very rare for spiral galaxies and are usually associated with massive elliptical galaxies.
- The radio jets are preventing stars from forming near the galaxy's center and are heating up nearby gases, inhibiting the collapse of new stars.
- Studying these rare galaxies could help scientists understand the relationship between supermassive black holes and their host galaxies.
