NASA took to Instagram to share an image that showed the remnants of a supernova, a large explosion that takes place at the end of a star’s life cycle. And, it is indeed remarkable. NASA said the event was created by the death (explosion) of a white dwarf star. A white dwarf is usually stable. But in a binary system, where two stars are orbiting each other, a white dwarf gravitational pulls matter from its companion and then explodes. A similar thing happened with this star.

NASA said in the post, “astronomers suspect this white dwarf star was more massive than expected, which also means it would have died earlier in its lifecycle.”

Named DEM L249, this white dwarf was located in the Large Magellanic Cloud, nearly 200,000 light-years away from Earth. The Hubble Space Telescope found it while “searching for surviving companions of white dwarf stars that went supernova in the Magellanic Cloud.”

The cosmic ribbons of gas, depicted in the image in red, have been left behind by the titanic stellar explosion. “A true chart-topper, this supernova remnant was found to have hotter gas and shine brighter in X-rays than the remnant of a typical Type 1a supernova,” the agency said on the Instagram post.

Separately, NASA explained via animation how a white dwarf star steals material away from a nearby stellar companion. When it reaches critical mass, it is no longer able to sustain its own mass and hence the star explodes and dies, creating a Type 1a supernova.

The Hubble telescope, a joint collaboration of NASA and the European Space Agency, was launched in 1990. It has since been one of the most relied on tools for space observation by scientists as the telescope has an unobstructed view of deep space.

Musk's Neuralink Will Test Brain Chips in Clinical Study in Great Britain

Elon Musk’s brain implant company Neuralink said on Thursday it will launch a clinical study in Great Britain to test how its chips can enable patients with severe paralysis to control digital and physical tools with their thoughts.

The company is partnering with the University College London Hospitals trust and Newcastle Hospitals to conduct the study, it said in a post on X.

Neuralink said patients living with paralysis due to conditions such as spinal cord injury and a nervous system disease called Amyotrophic Lateral Sclerosis (ALS) qualify to participate in the study.

The company raised $650 million (roughly Rs. 5,676 crore) in its latest funding round last month. It began human trials in 2024 on its brain implant after resolving safety concerns flagged by the US Food and Drug Administration, which had initially rejected Neuralink’s application in 2022.

According to the company, five patients with severe paralysis are currently using its device to control digital and physical tools with their thoughts.

Neuralink, founded in 2016, has raised about $1.3 billion (roughly Rs. 11,360 crore) from investors and is valued at roughly $9 billion (roughly Rs. 78,714 crore), according to media reports, citing PitchBook.

MIT Just Proved Einstein Wrong in the Famous Double-Slit Quantum Experiment

Physicists at MIT conducted a precise version of the renowned double slit quantum experiment, which challenges Einstein’s objections to quantum mechanics. With the help of ultracold atoms and single photons, they have shown the reaction of the long-standing wave-particle duality discussion without traditional spring setups. The researchers ignored the classical apparatus components and allowed nature’s inherent uncertainty to unleash Bohr’s complementarity, as both wave and particle-like behaviour cannot be observed simultaneously. The finding matches the quantum theory and disagrees with Einstein’s local realistic expectations.

MIT’s Quantum Experiment Challenges Einstein’s Classical View

As per Sci Tech Daily, Einstein argued for the deterministic reality, and claimed that the particles must be definite properties irrespective of the observation and that nothing could travel faster than light. With the Copenhagen interpretation, Bohr held the views which posit that only measurement defines the physical reality, along with complementary properties such as wave and particle behaviour, which are exclusive. The result of MIT supports this interpretation by Bohr.

With the removal of spring elements and the intrinsic quantum uncertain reliability of the ultracold atoms, MIT has sidestepped classical interference artefacts. Through this design, the experiment cleanly isolates the quantum effects and makes the result more robust and vague. Their behaviour demonstrates the dual nature when the individual photons pass through this experiment.

Bohr’s Complementarity Confirmed: Nature Obeys Quantum Rules

The findings through this experiment not only give the mechanical predictions and however, but also reinforce the significance of the theorem by Bell. Experiments done by Delft and Aspect have questioned the inequabilities under restricted conditions, strongly discrediting the hidden variable arguments of Einstein.

In a nutshell, MIT’s ultra double-slit experiment provides compelling evidence against the local realism of Einstein but in favour of the indeterminacy of quantum. Through the demonstration of the complementarity of the minimal classical interference, it is clear that the experiment underscores that nature follows the rules of quantum mechanics.

PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued

PSR J0922+0638 is one of the pulsars, which are typically ultradense remains of a massive star that exploded as a supernova. These are quite compact and lie a few miles away; however, they carry more weight than several other suns. Their density infers that the internal matter is packed tightly, and the borders diverge toward the black hole. However, the collapse of these stars is prevented due to the pressure from the quantum forces. Neutrons and protons smash together at the time of extreme densities, and then they create a single gigantic atomic nucleus. However, the core of the neutron stars is still a mystery.

Unraveling the Structure and Rotation of PSR J0922+0638

As per space report, these dense stars act as giant atomic nuclei together with the neutrons and protons pulled together under the gravity. One of the behaviours of pulsars is their rotation, which is stable. For example, PSR J0922+0638 rotates after every 0.43063, and this continues for thousands of years.

Astronomers studied the data from over 22 years to further understand the stability. The data was collected from South Africa’s MeerKAT array and China’s Nanshan Radio Telescope array. Although the changes were minuscule, even less than a billionth, the stars show an energy shift because of the intense physical forces. The scientists found a dozen glitches that we call a little change in the rate of rotation. The glitches followed a cycle in which rotation repeats after every 550 days.

Glitches, Magnetic Cycles, and the Mystery Within Pulsars

Furthermore, due to sudden glitches, a slow and cyclic speeding up and slowing down of the spin of the pulsar was seen during a 500-600-day period. This behaviour made the scientists question the glitches and the time variations of the pulsar, with the unawareness of the exact cause.

The theories put forward by the scientists comprise the magnetic cycle, which is similar to the movement of the superfluid in the star or the sun. Even after these theories, the internal mechanics of a pulsar are speculative. Further, long-term observations are important to know these secrets.
