The last total lunar eclipse of the year is set to take place on Tuesday, when the Earth blocks the Sun’s rays from reaching the Moon. Also known as the Blood Moon, the lunar eclipse will take place almost a year after the last total lunar eclipse, and viewers in North America, Central America, most of South America, the Pacific Ocean, Australia, New Zealand, and Asia will see the Moon darken and acquire a reddish hue on Tuesday. This will be the last total lunar eclipse until March 14, 2025.

How to watch the lunar eclipse

The Moon will traverse the northern half of Earth’s shadow, with totality predicted to last 86 minutes. Mid-eclipse happens on November 8th at 10:59 Universal Time (UT) or 4:29pm IST, around six days before apogee, when the Moon is farthest from Earth in its orbit. The actual clock times of the eclipse depend on your time zone.

You don’t need any equipment to observe a Blood Moon, but binoculars or a telescope can help enhance the view and the red colour of Earth’s only natural satellite.

What to expect from the lunar eclipse

As a result, during the eclipse, the Moon will appear 7 percent smaller than it does when it’s at perigee (closest to Earth), but the difference is imperceptible. The eclipse on Tuesday will be a bit brighter than the one that occurred in May — especially in the Moon’s northern half — since the Moon doesn’t glide as close to the dark center of Earth’s shadow.

There are several delightful extras viewers can look out for while admiring the eclipse. During totality, Earth’s shadow dims the Moon sufficiently for stars to be visible right up to its edge. In addition, Uranus reaches opposition just a day after the eclipse, when it’s directly opposite the Earth from the Sun and at its closest and brightest.

And on eclipse night the distant planet will be upper left of the red-hued Moon — binoculars will reveal the planet’s pale disk. The farther west you are, the smaller the gap between planet and Moon. Also, the Northern and Southern Taurid meteor showers peak around this time, so eclipse-watchers might be treated to a few meteors streaking across the night sky.

All stages of the eclipse occur simultaneously for everyone, but not everyone will see the full eclipse. Weather permitting, observers in western North America will witness the entirety of the event on the morning of November 8, with the partial eclipse phase beginning an hour or so after midnight. In Hawai’i, the eclipsed Moon will be directly overhead. Viewers in the central parts of the continent will see all of totality and most of the final partial phases, while those on the East Coast can watch the Sun rise as totality ends.

South America will witness the initial phases of the eclipse up to totality, while Central America can enjoy the show a bit longer and see it through the total phase. The eclipse is an early evening event in central and eastern Asia, Australia, and New Zealand, and the Moon rises either during the earlier partial phases or during totality.

What to observe during the lunar eclipse.

The Moon’s leading edge enters the pale outer fringe of Earth’s shadow: the penumbra. You are unlikely to notice anything until the Moon is about halfway across the penumbra.

  1. Watch for a slight darkening on the Moon’s left side as seen from North America. The penumbral shading becomes stronger as the Moon moves deeper in.
  2. The penumbra is the region where an astronaut standing on the Moon would see Earth covering only part of the Sun’s disc.
  3. The Moon’s leading edge enters the umbra, the cone of Earth’s shadow within which the Sun’s completely hidden. You should notice a dramatic darkening on the leading edge of the lunar disk. With a telescope, you can watch the edge of the umbra slowly engulfing one lunar feature after another, as the entire sky begins to grow darker.
  4. The trailing edge of the Moon slips into the umbra for the beginning of total eclipse. But the Moon won’t black out completely: It’s sure to glow some shade of intense orange or red.
  5. Why is this? The Earth’s atmosphere scatters and bends (refracts) sunlight that skims its edges, diverting some of it onto the eclipsed Moon. If you were on the Moon during a lunar eclipse, you’d see the Sun hidden by a dark Earth rimmed with the reddish light of all the sunrises and sunsets ringing the world at that moment.
  6. The red umbral glow can be quite different from one eclipse to the next. Two main factors affect its brightness and hue. The first is simply how deeply the Moon goes into the umbra as it passes through; the center of the umbra is darker than its edges. The other factor is the state of Earth’s atmosphere. If a major volcanic eruption has recently polluted the stratosphere with thin global haze, a lunar eclipse can be dark red, ashen brown, or occasionally almost black.
  7. In addition, blue light is refracted through Earth’s clear, ozone-rich upper atmosphere above the thicker layers that produce the red sunrise-sunset colors. This ozone-blue light tints the Moon also, especially near the umbra’s edge. You’ll need binoculars or a telescope to see this effect.
  8. As the Moon progresses along its orbit, events replay in reverse order. The Moon’s edge re-emerges into the sunlight, ending totality and beginning a partial eclipse again.
  9. When all of the Moon escapes the umbra, only the last, penumbral shading is left. Sometime later, nothing unusual remains.

Scientists Recreate Cosmic Ray Physics Using Cold Atom in New Laboratory Study

For the first time, researchers have managed to simulate a fundamental process of cosmic particle acceleration in a laboratory: the first series of discoveries that will transform our understanding of cosmic rays. Now, scientists from the Universities of Birmingham and Chicago have created a tiny, 100-micrometre Fermi accelerator, in which mobile optical potential barriers collide with trapped atoms, in a partial replica of how cosmic particles pick up energy in space. The technique not only replicates cosmic ray behaviour but also sets a new benchmark in quantum acceleration technology.

Lab-Built Fermi Accelerator Using Cold Atoms Validates Cosmic Ray Theory and Advances Quantum Tech

As per findings published in Physical Review Letters, this fully controllable setup demonstrated particle acceleration through the Fermi mechanism first proposed by physicist Enrico Fermi in 1949. Long theorised to underlie cosmic ray generation, the process had never been reliably replicated in a lab. By combining energy gains with particle losses, researchers created energy spectra similar to those observed in space, offering the first direct validation of Bell’s result, a cornerstone of cosmic ray physics.

In Fermi acceleration, ultracold atoms are accelerated to more than 0.5 metres per second using laser-controlled barriers. Dr Amita Deb, a coauthor and researcher at the University of Birmingham, mentioned, ‘Our chimney is more powerful than conventional quantum nano-measurements, which are the best acceleration tools in the world so far, and while its simplicity and small size can be compelling, its lack of a theoretical speed limit is the most attractive feature.’ The ultracold atomic jets could be readily controlled with high precision in the subsequent experiments.

This progress means that, for the first time, complicated astrophysical events like shocks and turbulence can be studied in a laboratory, lead author Dr Vera Guarrera stated. This opens new avenues for high-energy astrophysics and also for applications in quantum wavepacket control and quantum chemistry.

Researchers plan to find out how different behaviour affects energy cutoffs and acceleration rates. A compact Fermi accelerator of this type could be a cornerstone for studies of fundamental physics and also connect to emerging technologies such as atomtronics.

Scientists Say Dark Matter Could Turn Failed Stars Into ‘Dark Dwarfs’

Astronomers now propose that “failed stars” known as brown dwarfs could be powered by dark matter. Dark matter makes up about 85 percent of the universe’s matter but does not shine; it interacts only via gravity. Brown dwarfs form like stars but lack enough mass to ignite fusion. The theory suggests brown dwarfs in galaxy centers might trap dark matter in their interiors. When that dark matter annihilates, it releases energy that heats the star, turning the dwarf into a brighter “dark dwarf.” If such objects exist, finding them would give scientists a new clue to the nature of dark matter.

Dark Matter in Failed Stars

According to the new model, dense brown dwarfs at the centers of galaxies act like gravity wells that accumulate dark matter. Because dark matter interacts only via gravity, it naturally drifts to galactic cores, where it can be captured by star. As University of Hawai‘i physicist Jeremy Sakstein explains, once inside a star dark matter can annihilate with itself, releasing energy that heats the dwarf. The more dark matter a brown dwarf collects, the more energy it outputs. Crucially, this effect only works if dark matter particles self-annihilate (as with heavy WIMPs); lighter or non-interacting candidates like axions would not create dark dwarfs.

They propose using a chemical signature: a dark dwarf should hold on to lithium-7 that normal brown dwarfs burn away. The researchers say powerful telescopes like NASA’s James Webb Space Telescope might already be sensitive enough to spot cool, dim dark dwarfs near the Milky Way’s center. Detecting even one would strongly suggest that dark matter is made of heavy, self-interacting particles (like WIMPs).

In related work, Colgate astrophysicist Jillian Paulin coauthored studies of ancient “dark stars” fueled by dark matter, while SLAC physicist Rebecca Leane and collaborators have shown that dark matter capture could heat brown dwarfs and exoplanets – a process called “dark kinetic heating”. Together, these ideas highlight how even dim, unusual stars could illuminate the nature of dark matter.

New Gel-Based Robotic Skin Feels Touch, Heat, and Damage Like Human Flesh

Researchers have created a novel electronic “skin” that could let robots experience a sense of touch. This low-cost, gelatin-based material is highly flexible and durable and can be molded over a robot hand. Equipped with electrodes, the skin detects pressure, temperature changes, and even sharp damage. In tests it responded to pokes, burns and cuts. Unlike conventional designs that use separate sensors for each stimulus, this single “multi-modal” material simplifies the hardware while providing rich tactile data. The findings, published in Science Robotics, suggest it could be used on humanoid robots or prosthetic limbs to give them a more human-like touch.

Multi-Modal Touch and Heat Sensing

According to the paper, unlike typical robotic skins, which require multiple specialized sensors, the new gel acts as a single multi-modal sensor. Its uniform conductive layer responds differently to a light touch, a temperature change or even a scratch by altering tiny electrical pathways. This design makes the skin simpler and more robust: researchers note it’s easier to fabricate and far less costly than conventional multi-sensor skins. In effect, one stretchy sheet of this material can replace many parts, cutting complexity while maintaining rich sensory feedback.

Testing the Skin and Future Applications

The research team tested the skin by casting the gel into a human-hand shape and outfitting it with electrodes. They put it through a gauntlet of trials: blasting it with a heat gun, pressing it with fingers and a robotic arm, and even slicing it open with a scalpel. Those harsh tests generated over 1.7 million data points from 860,000 tiny conductive channels, which fed into a machine-learning model so the skin could learn to distinguish different types of touch.

UCL’s Dr. Thomas George Thuruthel, a co-author of the study, said the robotic skin isn’t yet as sensitive as human skin but “may be better than anything else out there at the moment.” He noted that the material’s flexibility and ease of manufacture as key advantages. Moreover, the team believes this technology could ultimately help make robots and prosthetic devices with a more lifelike sense of touch.
