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.

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.
How can there not be life out there?
Staggeringly huge amount of planets around those stars.
Trick is, is it alive during our ability to find it?
Too much to search. Not enough tine. Such a paradox.

“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.
Sometimes I think we’ve been created to just appreciate the universe!

Somewhere there, among the 100 million stars, I’m hoping fervently that there is another telescope trained at the Milky Way trying to figure out if they can spot somebody.

We’re just mere specs in all the galaxies. So much more out there, that we will never know about.

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.
Aditya L1 Solar Mission Begins Studying Energetic Particles in Solar Wind
After India’s solar mission, Aditya L1 began its journey towards Lagrange point 1 following a key manoeuvre, it has started studying energetic particles in the solar wind from space and will continue to do so for the rest of its life, a senior astrophysicist said. The study of the solar wind, the continuous flow of charged particles from the sun which permeates the solar system, will be carried out with the help of a device named Supra Thermal & Energetic Particle Spectrometer (STEPS), a part of the Aditya Solar wind Particle Experiment (ASPEX) payload.
“STEPS is now working from space. However, it was not sitting idle earlier. It has started functioning from within the magnetic field of the Earth since September 10 when Aditya was 52,000 kilometres above our planet,” Dr Dibyendu Chakrabarty, professor of Space and Atmospheric Sciences at the Physical Research Laboratory (PRL) said.
STEPS was developed by the PRL with support from the Space Application Centre (SAC) in Ahmedabad.
“During the travel time of four months (till Aditya L1 reaches its destination), it will study energetic particles in the solar wind. The data will help maintain the health and performance of our space assets in a better way,” Dr Chakrabarty told PTI.
The key aim of STEPS is to study the environment of energetic particles from the spacecraft’s position on the L1 point till it will function, he said. “The data from STEPS in the long term will also help us understand how space weather changes,” the space scientist said.
STEPS comprises six sensors, each observing in different directions and measuring supra-thermal and energetic ions. The data collected during the Earth’s orbits helps scientists to analyse the behaviour of particles surrounding the planet, especially in the presence of its magnetic field.
Aditya-L1, launched by the Indian Space Research Organisation (ISRO) on September 2, will go up to the First Lagrangian point, about 1.5 million km from the Earth ISRO on September 18 said on X: “Off to Sun-Earth L1 point! The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point.” Lagrangian points are where gravitational forces, acting between two objects, balance each other in such a way that the spacecraft can ‘hover’ for a longer period of time.
The L1 point is considered the most significant of the Lagrangian points, for solar observations, which were discovered by mathematician Joseph Louis Lagrange.
Elon Musk’s Neuralink Receives Approval to Start Brain Implant Human Trial
Billionaire entrepreneur Elon Musk‘s brain-chip startup Neuralink said on Tuesday it has received approval from an independent review board to begin recruitment for the first human trial of its brain implant for paralysis patients.
Those with paralysis due to cervical spinal cord injury or amyotrophic lateral sclerosis may qualify for the study, it said but did not reveal how many participants would be enrolled in the trial, which will take about six years to complete.
The study will use a robot to surgically place a brain-computer interface (BCI) implant in a region of the brain that controls the intention to move, Neuralink said, adding that its initial goal is to enable people to control a computer cursor or keyboard using their thoughts alone.
The company, which had earlier hoped to receive approval to implant its device in 10 patients, was negotiating a lower number of patients with the US Food and Drug Administration (FDA) after the agency raised safety concerns, according to current and former employees. It is not known how many patients the FDA ultimately approved.
Musk has grand ambitions for Neuralink, saying it would facilitate speedy surgical insertions of its chip devices to treat conditions like obesity, autism, depression and schizophrenia.
In May, the company said it had received clearance from the FDA for its first-in-human clinical trial when it was already under federal scrutiny for its handling of animal testing.
Even if the BCI device proves to be safe for human use, it would still potentially take more than a decade for the startup to secure commercial use clearance for it, according to experts.

ISRO’s Aditya-L1 Performs TL1I Manoeuvre, Set to Reach Sun-Earth L1 Point
The Indian Space Research Organisation (ISRO) announced on Tuesday that its maiden solar mission — Aditya-L1 — has performed the Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre successfully and the spacecraft was now in a trajectory that will take it to the Sun-Earth L1 point. ISRO also informed that it marked the fifth consecutive time that the ISRO had successfully transferred an object on a trajectory toward another celestial body or location in space.
A post on the ISRO official handle on social media platform X read, “Aditya-L1 Mission | Off to Sun-Earth L1 point | The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a manoeuvre after about 110 days. This is the fifth consecutive time ISRO has successfully transferred an object on a trajectory toward another celestial body or location in space.”
Earlier, a launcher carrying the Aditya-L1 spacecraft blasted off from the Satish Dhawan Space Station at Sriharikota in Andhra Pradesh. The primary objectives of India’s maiden solar mission include collecting scientific data and marking another milestone in India’s solar exploration efforts.
The agency had earlier posted on X, “Aditya-L1 Mission: Aditya-L1 has commenced collecting scientific data. The sensors of the STEPS instrument have begun measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth. This data helps scientists analyze the behaviour of particles surrounding Earth. The figure displays variations in the energetic particle environment, collected by one of the units.”
The Supra Thermal and Energetic Particle Spectrometer (STEPS) instrument, a part of the Aditya Solar Wind Particle Experiment (ASPEX) payload, also started its data-gathering operations earlier.
