The night skies across the United States are set to host a breathtaking natural event as the Milky Way, our home galaxy, will be especially visible during the final days of May, coinciding with the Memorial Day weekend, as mentioned in a report by USA Today. Astronomers suggest that a combination of moon phases and atmospheric clarity will allow for remarkable views of the galaxy's luminous arc stretching across the heavens. For space enthusiasts and casual stargazers alike, this period offers an ideal window to observe the galactic core — a rare sight under perfect conditions, away from city lights and during moonless hours.The Milky Way, classified as a barred spiral galaxy, spans over 100,000 light-years and houses billions of stars, including our Sun. Earth is situated in one of the galaxy's spiral arms, about halfway between the dense central bulge and the outer edge. From our perspective, the galaxy appears as a soft, glowing band of light sweeping from horizon to horizon, giving it the name "Milky Way."As part of a galactic neighborhood known as the Local Group — which also includes the Andromeda Galaxy — the Milky Way is a major structure in our visible universe. Though omnipresent in the night sky, seasonal and lunar variations influence how clearly it can be seen.According to astronomical sources, the most favorable period to witness the Milky Way in all its glory will be between May 20 and May 30, 2025, as per the USA Today report. This timeframe spans the days between the last quarter moon and the new moon, when lunar brightness is at its lowest, allowing starlight to stand out more prominently.The upcoming new moon on Tuesday, May 27 — just after Memorial Day — will mark the peak of these optimal stargazing conditions. Skies will be darkest between midnight and 5 a.m., creating a perfect window for viewing.In the Northern Hemisphere, including all of the continental United States, the Milky Way rises in the southeast, traverses the southern sky, and sets in the southwest. Stargazers are encouraged to seek locations far from artificial light sources. Resources such as DarkSky International provide listings of designated dark sky areas — with over 150 certified sites across the U.S.To locate the galaxy more easily, observers can use the 'Summer Triangle,' a celestial feature made up of three bright stars that align with the Milky Way's arc. Astronomy guides recommend checking weather forecasts and choosing cloud-free nights to improve visibility.A combination of favorable moon phases (leading up to a new moon on May 27) and generally clear atmospheric conditions will make the Milky Way's galactic core more visible during the nights of May 20 to May 30, 2025.The darkest and clearest viewing window is between midnight and 5 a.m., especially on moonless nights near the new moon (May 27). These hours offer the highest contrast against light pollution and moonlight.

How To Find Planet B, And Get There Alive
Earth will have a meltdown. What are our options? Tardigrades are little critters that were around before dinosaurs, and will eventually outlast us on Earth. They are so tough they can survive exposure to -272°C (cooler than liquid helium) and 150°C, which is quite a bit hotter than your pressure cooker. And Earth will be hotter than that in a few hundred million years – not entirely because of your car's tailpipe emissions. As our Sun grows older, it will expand, making Earth hot like Venus with its middle-age spread. So, we should start planning our escape now. But where can we go? Lisa Kaltenegger's book Alien Earths has useful pointers for wannabe galactic hitchhikers. As the founding director of Carl Sagan Institute at Cornell University, Kaltenegger is an authority, but she's got no recommendations, yet. Ideally, you wouldn't want to travel too far because you are – as The Matrix's Agent Jones put it – 'only human'. How long will you live – 100, 120 years? Unless you hit Star Trek's fantastical 'warp speed' – faster than light – you can't go far in that time. Voyagers 1 & 2 left Earth in 1977, and they won't get close to another star for 40,000 years. So, space travel's a bummer. Besides, space is mostly empty. Looking out the window will mean death by boredom. Step on the gas, and a 1mg speck of space dust could destroy your ship. So, speed and time are not on your side. Worse, your choice of space rock is a gamble. You have chosen it based on signs like the signature of its light, which tells you something about temperature on the planet's surface and the materials you'll find on it. Say, everything's perfect, and this planet circles our Sun's nearest neighbour, Proxima Centauri, which is about 40tn km away. You gather bag, baggage, family, and everything else that Moses took, and set sail on your ark. But…that light signal from Proxima took four years to reach Earth. Your data was already four years old. By the time you get there – cryofrozen, probably – in, say, 40,000 years, that planet may have ceased to exist. What then? The choice of your future home is complicated by other factors also, Kaltenegger shows. Maybe you're looking too hard for an Earth-like planet and missing some gems. You want oxygen? Earth had precious little in its atmosphere till cyanobacteria appeared over 2bn years ago. They could split water, use hydrogen and free up oxygen. That's how oxygen increased in air. If Earth formed at 12am, atmospheric oxygen touched 15% concentration only at 10pm. And now, a few seconds before midnight, it's at 21%. So, by looking for ready oxygen, you might miss some good candidate planets. Likewise, searching only for a planet with green plants might be a mistake. Plants on Earth are green because sunlight is strong and they absorb its red and violet wavelengths, while reflecting the green. But on a liveable planet around a red star – whose light has less energy – plants may need to absorb all the available light. Hence, their leaves could appear black! Our next 'Earth' will definitely need some getting used to. There's so much to figure out and fix. But we can't do that if we make this Earth unlivable in the next decade or two.

Rare superorganism ‘wormnadoes' caught on camera for the first time; what is it exactly?
TIL Creatives When facing starvation and low oxygen, tiny aquatic worms unite to form writhing towers that move like a single superorganism. Known as 'wormnadoes,' this behavior was previously observed only in lab settings, but recent wild footage reveals how these creatures cooperate to survive extreme environments. When faced with starvation and low oxygen, some creatures don't just fight to survive; they unite. Tiny aquatic worms, barely visible to the eye, crawl toward one another and create writhing towers that move in sync like a single, squirming superorganism. This extraordinary behavior, known only from lab studies until recently, has now been filmed in the wild, shedding light on a remarkable natural squirming formations, sometimes nicknamed 'wormnadoes,' had previously been seen only in laboratory experiments. Now, their appearance in natural conditions offers fresh insights into how some animals work together to survive extreme environments. Also Read: Space's 'Bermuda Triangle' growing as mysterious force under Earth's outer core may cripple International Space Station, NASA perplexed The phenomenon was first captured by a group of researchers from the University of Massachusetts Amherst and the Georgia Institute of Technology. They observed these worm towers while studying aquatic blackworms (Lumbriculus variegatus) in their natural habitat. The worms, which are typically found in shallow freshwater bodies, were seen forming wriggling vertical columns, appearing almost like a single moving entity. This behavior is described as a form of 'active matter aggregation,' where individual organisms come together to act as a single, coordinated unit. These towers behave like superorganisms—structures made up of many organisms acting as one body. According to researchers, this form of collective behavior is a survival strategy. The worm towers were mostly observed in response to environmental stress, such as decreasing oxygen levels or changes in water temperature. By bundling together, the worms can reach the water's surface where oxygen is more plentiful. In some cases, these towers even moved as a group, flowing across a surface in search of better conditions. Watch video: The discovery in nature confirms earlier lab experiments, where researchers simulated harsh environments and noticed blackworms clumping together into blob-like masses. These blobs can adapt shape and flow in response to their environment, showing flexibility and coordination. The new observations suggest that the same behavior happens outside the lab—something scientists had not witnessed worm plays a role in the tower's movement and stability. As one worm moves, it can drag others with it. The coordination allows the mass to behave like a single structure, making it more efficient at reacting to environmental threats and changes. Also Read: Sun will die in 5 billion years but life could survive on Jupiter's moon Europa; here's how The implications of this finding go beyond biology. Understanding how simple organisms coordinate could inspire new ideas in robotics and swarm engineering. For example, scientists could design soft robots that mimic worm tower behavior, adjusting their shape and movement based on external study of these worm towers opens a window into the complexity of group behavior in even the simplest life forms. While it might look chaotic to the human eye, the movement is highly organized and purposeful. Researchers now aim to study other species that might show similar collective behaviors in the wild. Perez and her team at the Max Planck Institute of Animal Behavior further studied this behavior under laboratory conditions to understand the sensory and environmental cues that drive it. Their findings could help decode the mechanics behind such coordinated survival strategies and their broader ecological roles.

Astronomers Uncover Most Powerful Explosion Since The Big Bang
Astronomers from the University of Hawai'i's Institute for Astronomy have identified a new class of cosmic explosions, termed "extreme nuclear transients" (ENTs), marking the most energetic events observed since the Big Bang. These phenomena occur when massive stars, at least three times the mass of our Sun, are torn apart by supermassive black holes at the centres of distant galaxies. The resulting explosions release energy equivalent to what 100 Suns would emit over their entire lifespans, making them visible across vast cosmic distances. This discovery offers new insights into the dynamic interactions between stars and black holes in the universe. The team's findings were detailed today in the journal Science Advances. "We've observed stars getting ripped apart as tidal disruption events for over a decade, but these ENTs are different beasts, reaching brightnesses nearly ten times more than what we typically see," said Jason Hinkle, in a statement, who led the study as the final piece of his doctoral research at IfA. "Not only are ENTs far brighter than normal tidal disruption events, but they remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions." The immense luminosities and energies of these ENTs are truly unprecedented. The most energetic ENT studied, named Gaia18cdj, emitted an astonishing 25 times more energy than the most energetic supernovae known. While typical supernovae emit as much energy in just one year as the sun does in its 10 billion-year lifetime, ENTs radiate the energy of 100 suns over a single year. As per a news release by W M Keck Observatory, ENTs were first uncovered when Hinkle began a systematic search of public transient surveys for long-lived flares emanating from the centres of galaxies. He identified two unusual flares in data from the European Space Agency's Gaia mission that brightened over a timescale much longer than known transients and without characteristics common to known transients. "Gaia doesn't tell you what a transient is, just that something changed in brightness," said Hinkle. "But when I saw these smooth, long-lived flares from the centres of distant galaxies, I knew we were looking at something unusual."
