NASA has identified the cause of the anomalous data transmissions from Voyager 1, attributing it to a malfunctioning computer memory chip. Efforts are underway to develop a solution to bypass the malfunctioning component and restore normal operations. The issue, which began affecting data in November, highlights the challenges of managing spacecraft technology over extended interstellar missions. Further updates will be provided as the engineering team progresses with their corrective actions. For detailed information, please visit the official NASA Voyager blog. @Sci_Strangeries

Voyager 1 Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun's heliosphere. It was launched 16 days after its twin Voyager 2. It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to Earth. Real-time distance and velocity data is provided by NASA and JPL. At a distance of 162.7 AU (24.3 billion km; 15.1 billion mi) from Earth as of May 2024, it is the most distant human-made object from Earth. The probe made flybys of Jupiter, Saturn, and Saturn's largest moon, Titan. NASA had a choice of either doing a Pluto or Titan flyby; exploration of the moon took priority because it was known to have a substantial atmosphere. Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons.

Cotard's syndrome Cotard's syndrome, also known as “walking corpse syndrome”, is where people hold the delusional belief that they are dead and do not exist. Others believe that body parts are missing.

The Boötes Void The Boötes Void (colloquially referred to as the Great Nothing) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing only 60 galaxies instead of the 2000 that should be expected from an area this large, hence its name. With a radius of 62 megaparsecs (nearly 330 million light-years across), it is one of the largest voids in the visible universe, and is referred to as a supervoid. It was discovered in 1981 by Robert Kirshner as part of a survey of galactic redshifts. Its centre is located 700 million light-years from Earth. @Sci_Strangeries

The Big Splat In the far future, galaxies will eventually drift so far apart that light from one can never reach another. In fact, as stars get old and die, a time will come when there's no light — or heat — left. The universe will be a dark, cold, empty void. It sounds like the end of everything, but according to one theory, it's actually the beginning of the next universe in an endlessly repeating cycle. Remember the braneworld theory? This is what happens when one cold, empty brane collides with another — which, given enough time, it's bound to do eventually. Cosmologists Neil Turok and Paul Steinhardt believe such a collision would generate enough energy to create a whole new universe. They call this the "ekpyrotic theory," though physicist Michio Kaku has more evocatively dubbed it the "Big Splat." @Sci_Strangeries

Size Comparison If Earth were the size of a tennis ball, the Sun would be a sphere 24 feet across, approximately 0.5 mile away. @Sci_Strangeries

Comets A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions.

Vigro Supercluster The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which itself contains the Milky Way and Andromeda galaxies, as well as others. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years). The Virgo SC is one of about 10 million superclusters in the observable universe and is in the Pisces–Cetus Supercluster Complex, a galaxy filament. A 2014 study indicates that the Virgo Supercluster is only a lobe of an even greater supercluster, Laniakea, a larger, competing referent of the term Local Supercluster centered on the Great Attractor.

Roko's Basilisk The concept of Roko's Basilisk is a thought experiment that involves the potential development of an all-powerful Artificial Intelligence (AI) entity. The theory proposes that such an entity could punish individuals who were aware of its creation but failed to contribute to its development. This idea has sparked significant controversy and has led to debates about the ethical implications of AI and the potential risks of AI development. @Sci_Strangeries

Phoenix A is the biggest black hole ever discovered. The black hole was initially detected in 2010. it’s located in the Phoenix Cluster 8,500,000,000 light years away. It's size is approximately 100,000,000,000 solar masses + with the Schwarzschild diameter of 590.5 billion kilometers, it dethroned TON-618 by a staggering 34 billion solar masses.There is no definite answer to this, though it probably formed around 10-100 million years after the big bang.The type of black hole Phoenix A is, is a Stupendously Large Black Hole (SLaBs) it's name is actually underestimating it.

The Universe has an average colour – and it’s called cosmic latte. In a 2002 study, astronomers found that the light coming from galaxies (and the stars within them) – alongside all the visible clouds of gas and dust in theUniverse – when averaged, would produce an ivory colour very close to white. They named this colour ‘cosmic latte’. The ‘beigeness’ of the Universe is because there are slightly more regions that produce red, yellow and green light than those that produce blue. Averaged over the entire sky, however, this beige colour is diluted and appears almost, but not entirely, black. Reference - https://www.sciencefocus.com/space/universe-average-colour-cosmic-latte
