Andromeda Galaxy’s vastness is captured perfectly in a zoom-out video that was shared by World and Science, a Twitter handle that frequently shares interesting stories from the world of science. The video of Andromeda Galaxy, also known as Messier 31 or M31, has left users on the micro-blogging site awestruck. The sharp zoom0out clip shows over 100 million celestial bodies. The clip begins with the camera moving to the right before it zooms out and reveals what’s undoubtedly a heavenly view of the M31.  

“Mind-blowing! A zoom out of the sharpest view of the Andromeda Galaxy ever, showing more than 100 million stars!” wrote World and Science on June 9 and shared the clip with its 2.1 million followers. Midway through the zoom out video, the camera slows down a bit and reveals the galaxy full of innumerable stars, some easily identifiable due to their size. At the time of writing, the video had already generated quite an excitement, with over 340,000 views, 10,500 likes, and over 3,200 retweets.

Reacting to it, Teen Wolf star Ian Bohen tweeted, “Great perspective for all those who think we’re alone out here,” he wrote.

Another user (@idealust) wondered how there could be no life out there. “Staggeringly huge amount of planets around those stars. The trick is, is it alive during our ability to find it? Too much to search. Not enough time. Such a paradox,” the tweet read.

“It’s also incredible to think how far apart these stars really are when they all look so close together in the photo,” user Chilly MIV commented

Here are some more reactions to the fascinating view of the Andromeda Galaxy.

According to NASA, the Andromeda galaxy is a majestic spiral of perhaps as many as 1 trillion stars, twice the number in our Milky Way. It’s so close to us that the galaxy appears as “a cigar-shaped smudge of light high in the autumn sky,” said the space agency. It added that the M31 is at a distance of 2.5 million light-years from us. 

In another post last month, NASA recalled that less than 100 years ago, many astronomers thought the Milky Way was the only galaxy in the universe. It said that even though astronomers debated the existence of other galaxies, it took Edwin Hubble’s observations of the Great Andromeda Nebula to confirm that it was far too distant to be part of the Milky Way. The Great Andromeda Nebula then became the Andromeda Galaxy, and astronomers recognised that our universe was much bigger than humanity could envision.

NASA to Launch Three Rockets in Alaska to Study Auroral Substorms’ Impact

An important mission is set to take place in Alaska. It aims to understand how auroral substorms impact the Earth’s upper atmosphere. Three rockets will be launched within a short window to observe the movement of air and changes in composition at high altitudes. Scientists seek to determine whether the heat from auroras causes vertical movement or if waves spread the energy across a wider area. The findings could improve space weather forecasting, which is crucial for satellites and communication systems.

Study Objective and Launch Plan

According to the reports from the experiment titled Auroral Waves Excited by Substorm Onset Magnetic Events (AWESOME), the rockets will be launched from Poker Flat Research Range. The facility, located 20 miles north of Fairbanks, is managed by the University of Alaska Fairbanks under a NASA contract. The launch window is open from 24 March to April 6.

A four-stage rocket and two two-stage rockets will be used. The first two will release tracers at specific altitudes to study wind movement. The third rocket will release vapour tracers at five different altitudes. The tracers, in pink, blue and white, should be visible for up to 20 minutes. Ground cameras will capture the data under specific lighting conditions.

Scientific Goals and Observations

Mark Conde, a space physics professor at the University of Alaska Fairbanks, leads the project. The experiment aims to determine how auroras affect air movement. One theory suggests vertical convection plays a key role, while another proposes that acoustic-buoyancy waves cause a broader atmospheric impact. The research could reshape current understanding and refine space weather models.

A team of graduate researchers will monitor the launches from various sites in Alaska, including Utqiagvik, Kaktovik, and Toolik Lake. The results may provide better insights into how auroral events alter atmospheric conditions and influence satellite-dependent technology.

Partial Solar Eclipse of March 2025: Satellite Images to Show Moon’s Shadow

Partial Solar Eclipse of March 2025: Satellite Images to Show Moon’s Shadow

A partial solar eclipse will take place on March 29, 2025. The moon will be passing in front of the sun. It will be visible from Europe, Western Africa, Eastern Canada and the Northeastern United States. From the ground, the sun will appear to have a portion covered by the moon. From space, weather satellites will capture the movement of the moon’s shadow across Earth. The eclipse will begin over the Atlantic Ocean, where the darkest part of the shadow will blend into the night side of Earth. In Nunavik, Quebec, the eclipse will reach its maximum, covering 94% of the sun at sunrise.

Satellite Observations of the Eclipse

According to reports, geostationary satellites will record the eclipse as the moon’s penumbral shadow moves across Earth. The Copernicus Sentinel-3, Himawari and GOES-16 satellites are expected to capture detailed images. The International Space Station may also document the event, as astronauts aboard have done in the past. The images taken will show the gradual movement of the shadow, which will appear darker in regions where the eclipse is most pronounced.

Movement of the Moon’s Shadow

As per NASA’s Scientific Visualisation Studio, the moon’s shadow will travel from west to east due to the moon’s orbital motion. It moves at a speed of 3,700 kilometres per hour, which is faster than Earth’s rotation. This causes the shadow to appear to move in the opposite direction of the sun’s apparent motion in the sky. The curvature of the Earth also affects the shadow’s speed and shape as it moves across different regions.

Viewing the Eclipse from Space

The satellites which are positioned at 36,000 kilometres above the Earth provide the best view of the event. These satellites will be capturing real-time images of the eclipse shadow as it moves. Astronauts aboard the International Space Station may also capture images of the eclipse from orbit.

Archaeologists Discover a 3,200-Year-Old Tomb Possibly Linked to Ramesses III

Archaeologists Discover a 3,200-Year-Old Tomb Possibly Linked to Ramesses III

A 3,200-year-old tomb has been found in northeastern Egypt. Researchewr believe that it may have belonged to a military commander who served during the reign of Ramesses III. Tthe location of the discovery was at the site known as Tell el-Maschuta. It was confirmed by the Egyptian Ministry of Tourism and Antiquities. The mud-brick tomb consists of a burial chamber along with three adjoining rooms. Among the artifacts found inside, a gold ring bearing the name of Ramesses III and a collection of bronze arrowheads have drawn particular attention. Other objects recovered include an ivory box and pottery vessels with inscriptions.

Artifacts Suggest Reuse of the Tomb

According to the ministry’s statement, some of the inscriptions on the pottery refer to Horemheb, a pharaoh who ruled between 1323 and 1295 B.C. Before becoming king, he was known for his military background. It is still not clear why his name appears on the artifacts. One possibility is that burial items from an earlier period were reused. Despite this, the presence of objects linked to Ramesses III has led experts to believe that the tomb was used during his reign, which lasted from around 1184 to 1153 B.C.

Experts Call for More Analysis

Speaking to Live Science, Anthony Spalinger, professor emeritus at the University of Auckland, said that further study of the inscriptions is necessary to have more details about the individual buried there. Egyptologist David Warburton from Northeast Normal University in China also pointed out that without titles in the inscriptions, it is difficult to confirm whether the person was a military commander. Meanwhile, Aidan Dodson, an Egyptology professor at the University of Bristol, suggested that the tomb may have been built during Horemheb’s reign and later reused during the time of Ramesses III and the Twenty-second Dynasty.
