Earthlings are set to witness a rare stellar phenomenon that happens once in approximately every 80 years. It is expected that a nova will take place soon in the coming months. Nova is referred to as an explosion in a binary star system.The star system in question is called T Coronae Borealis , or " T CrB ". It is composed of two stars that belong to two distinct categories: a white dwarf, and a red star. The upcoming eruption in T Coronae Borealis is likely to be visible to the naked eye for a brief period. The star system has been under the watch of astronomers for quite some time now.T Coronae Borealis, which is a part of the Northern Crown constellation, is located nearly 3,000 lightyears away from Earth. The periodic nova in the star system results from the over-accumulation of gases around the white dwarf. The impact of thermonuclear explosion only impacts the surface of the Earth-sized remnant.The gases that build up around the white dwarf over time are emitted by the red giant. The process takes several thousand years to complete a full cycle in most cases. However, in the case of T CrB, it does so in just 80 years, making it a lifetime event for most people.Past novae in the binary system are known to have occurred in 1787, 1866, and 1946. Prior to that, an outburst was likely recorded in 1217. The latest explosion in T CrB was earlier expected to take place in late 2024. However, that obviously did not happen. It is hard to predict when a Nova will exactly occur. In recent years, astronomers started observing T CrB when it appeared to lose its brightness.As per NASA , the anticipated nova eruption greatly interests astronomers as such events are relatively rare in Earth's vicinity. The outburst's proximity from Earth will enable scientists to observe the event in unusual detail. An average nova can be around 200,000 times brighter, as compared to the Sun. The brightest nova can be 10 times brighter than that, as per NASA.The nova explosion in T CrB repeats itself every 80 years or so.The last stellar explosion in T CrB was documented in 1946.

Ring of Fire awakens: 600-year-quiet volcano erupts after massive quake shakes Pacific
Krasheninnikov volcano's massive ash blast Live Events Scientists confirm earthquake link More eruptions could be coming FAQs (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel A massive 8.8 magnitude earthquake shook the Pacific last Wednesday. This was the 6th strongest quake ever recorded, according to the US Geological Survey. The quake's epicenter was 84 miles southeast of Russia's Kamchatka Peninsula, triggering tsunami warnings across the Pacific, USGS said according to media no major tsunami waves hit, eyewitness footage showed tragic videos of whales washed ashore, likely killed by the quake. Scientists say this quake has now triggered volcanic eruptions along the Pacific Ring of Fire, a huge horseshoe-shaped area filled with hundreds of volcanoes, Dr. Alexey Ozerov of Russian Institute of Volcanic and Seismic Sciences said as per Sopka, the largest volcano in the region, erupted just hours after the earthquake according to Russian geological sources quoted by reports. This was its first eruption in 600 years, as hot lava burst out violently, according to KVERT, according to the report by The Sunday evening, the Krasheninnikov volcano erupted, sending a giant ash cloud nearly 4 miles high into the sky as per Kamchatka Volcanic Eruption Response Team (KVERT). This eruption is considered "historic" by Local Russian media and geologists. The volcano last erupted between 1423 and 1503, making this its first known eruption in centuries, historical volcanic quickly issued a red aviation alert, warning aircraft of heavy ash in the sky , according to the KVERT official alert. As of Monday night, the eruption was still going on, with possible ash explosions reaching up to 10 km high according to emergency services update, as per the report by The Sun.A third volcano, Mutnovsky, started rumbling on Monday evening. A 'thermal anomaly' was spotted by scientists, which is often a sign of coming eruptions according to the Kamchatka Volcanic Eruption Response Team. People were strongly warned to stay away from the site, KVERT public warning Alexey Ozerov said there is a direct connection between the earthquake and the volcanic eruptions. He explained the quake "activated magmatic centers" and gave them extra energy, causing eruptions according to Dr. Ozerov's official statement, as per the report by The Jonathan Paul from Royal Holloway University, UK, said the quake likely opened cracks in the earth, which allowed magma to rise and build pressure — Interview with Daily Mail. He said the delay between the quake and eruptions like Krasheninnikov's happens because cracks take time to form — Dr. fear this could be just the beginning of more volcanic activity along the Ring of Fire — Volcanologists' assessments. Kamchatka alone has 160 volcanoes, many of them still active — Russian geological records, as mentioned by The Sun Michael Manga from UC Berkeley warned that volcanoes in Chile, US Cascades, Japan, Indonesia and Kamchatka are all prone to erupt after big quakes as per previous scientific findings, reports scientist Alexey Ozerov said a crack opened on Krasheninnikov's crater, releasing steam, ash, and gas. He said the ash spread to the Valley of Geysers, and there's a gas smell in the air, as per reports.. Ozerov warned tourists may need to be evacuated from the Valley of Geysers due to possible health and safety, as stated by The Sopka in Russia's Kamchatka Peninsula erupted for the first time in 600 years after a massive Pacific scientists confirmed the 8.8 magnitude Pacific quake caused multiple volcanoes to erupt along the Ring of Fire.

Perseids Meteor Shower Peak, Other Sky Events To Watch In August
Led by the Perseids meteor shower, August brings a busy skywatching calendar. With planetary pairings and deep-sky objects also on display, the month offers plenty for stargazers worldwide. August 12-13: Perseids Meteor Shower Peaks The Perseids, one of the most popular annual meteor showers, will peak on the night of August 12-13. While active from late July to August 24, this two-night window is expected to be the most intense, with up to 150 meteors per hour or 2-3 per minute, according to This year, the full moon on August 9 may interfere with viewing, washing out fainter meteors. Perseids Meteor Shower To Be Visible In India Viewers in India are advised to head to darker, rural areas for better visibility. Ideal viewing time is from midnight to just before sunrise on August 13. Regions such as Spiti, Ladakh, Rann of Kutch, and remote parts of Karnataka or Uttarakhand are recommended. Those who miss the peak may still catch a few meteors in the days following, especially between August 16 and 20, when moonlight begins to fade. August 26: Mars And The Moon Conjunction On August 26, Mars will appear next to a thin crescent moon in the western sky around 8.15 pm IST. Visible low on the horizon, the pair will stay close for about an hour. No telescope or binoculars are needed. Planetary Viewings August 11-12: Venus-Jupiter Conjunction Venus and Jupiter will appear only one degree apart in the eastern sky before sunrise, according to NASA's JPL. August 12 (early morning): Venus and Jupiter Rise Together Both planets will rise side by side, appearing like two bright stars. August 19-20: Crescent Moon With Venus and Jupiter A thin crescent moon will join the two planets in the eastern sky before sunrise. August 19: Mercury At Greatest Elongation Mercury will be at its most visible this month in the eastern sky before sunrise. It appears low on the horizon. The Dumbbell Nebula The Dumbbell Nebula (M27), one of the easiest planetary nebulae to spot, will be visible all month within the Summer Triangle, high overhead during early nights. It appears as a faint patch of light and marks the remains of a dying star. Mercury, Venus, Mars, Jupiter, and Saturn will be visible at various times this month. Mercury appears low in the east later in August, Venus and Jupiter shine bright in the eastern sky before sunrise, Mars is visible in the west after sunset, and Saturn rises late at night, shifting earlier as the month progresses.

‘Our processing system will turn that into drinking water': Learn how astronauts wash their hair in space
Washing hair in space is a unique challenge due to the lack of gravity. On Earth, we rely on running water to rinse out shampoo, but in the microgravity environment of the International Space Station (ISS), water behaves differently. In a video, NASA astronaut Karen Nyberg provided a step-by-step demonstration of how astronauts wash their hair while floating in zero gravity. To wash her hair in space, Nyberg uses a bag of warm water, no-rinse shampoo, a towel, and a comb. She explains, 'These are the things I need: a bag of warm water, a little no-rinse shampoo, a towel, and my comb.' Since water does not flow like on Earth, Nyberg has to squirt warm water directly onto her scalp. She describes, 'What I like to do is start by just putting some hot water, squirting it onto my scalp. I have a mirror there so I can kind of watch what I'm doing. Sometimes the water gets away from you, and you try and catch as much as you can. Then, I just work the water up through to the ends of my hair.' Astronauts use a special no-rinse shampoo, which does not require full rinsing. Nyberg explains, 'Next, I take my no-rinse shampoo and squirt it onto my scalp—just a little bit—and rub it in, again working it out to the ends. Sometimes, I'll actually take my comb to help work it all the way to the end.' Without running water, astronauts rely on towels to help remove dirt and excess shampoo. She says, 'I like to take my towel while I have the shampoo in there and just kind of work it because, without standing under running water, you need to use the towel a little bit to help get some of the dirt out.' Even though the shampoo is no-rinse, Nyberg finds that adding a little extra water helps with the cleaning process. 'I like to follow that by a little more water. It's called no-rinse shampoo, but I think it's best if you use a little water with it.' Once the hair is clean, it dries naturally in the weightless environment. The evaporating water is captured by the ISS's air conditioning system and eventually recycled into drinking water. 'Now, as my hair dries, the water evaporates and becomes humidity in the air. Then, our air conditioning system will collect that into condensate, and before long, our water processing system will turn that into drinking water.' After washing, Nyberg carefully combs through her hair to remove tangles and lets it dry freely. She notes, 'At the end, I just do one final comb-through to make sure there are no snarls and snags. While it dries, I like to let it stay free—I don't put it back in a ponytail while it's drying.' Washing hair in space requires patience and adaptation, but astronauts have developed efficient techniques to maintain hygiene while orbiting Earth. Nyberg's demonstration offers fascinating insight into daily life aboard the ISS, where even simple tasks like hair-washing require creative solutions.
