Recent studies, published in Physical Review D on September 16 and 17, have proposed that microscopic black holes may be present within the solar system, potentially affecting the paths of planets and satellites. These objects, referred to as primordial black holes, are thought to have formed during the early universe. Estimated to have asteroid-like masses but dimensions comparable to a hydrogen atom, they are being suggested as possible contributors to the enigma of dark matter, which constitutes 85 per cent of the universe’s matter.

Planetary Orbits and Primordial Black Holes

It has been theorised that primordial black holes originated from dense regions of the early universe collapsing under their own gravity. Unlike black holes formed from dying stars, these objects are significantly smaller and faster, with estimated speeds of approximately 200 kilometres per second., as per one of the research paper.

The gravitational effects of such black holes on planetary orbits are being studied. It was explained to Science News by Dr Sarah Geller, a cosmologist at the University of California, Santa Cruz, that the wobbles in a planet’s orbit around the Sun could be caused by the gravitational pull of a primordial black hole. A detailed modelling of the solar system has been planned by her team to explore this hypothesis.

Satellite Disturbances as a Detection Method

A separate method involving the observation of satellite movements has been proposed by Dr Sébastien Clesse of Université Libre de Bruxelles, alongside Dr Bruno Bertrand of the Royal Observatory of Belgium. It was suggested that small black holes could subtly alter satellite altitudes, which might allow their detection. Existing probes, it was stated, could potentially be used to measure such disturbances. The method was described as particularly effective for smaller black holes.

Limitations and Complications

The feasibility of detecting primordial black holes was questioned by Dr Andreas Burkert of Ludwig-Maximilians-University Munich. It was noted that other factors, such as solar winds or asteroid interactions, could mimic the gravitational effects attributed to black holes. It was further remarked that while the detection of these objects is considered rare, the possibility cannot be dismissed entirely.

The research has introduced promising approaches to uncovering these elusive objects, with the potential to address significant questions about the universe, including the nature of dark matter.

Ancient Praise for Pharaoh Ramesses II Found on Paris Obelisk, Egyptologist Claims

An Egyptologist claims that he has accidentally found a series of secret hieroglyphic inscriptions on an iconic 3300-year-old Egyptian obelisk in Paris. This inscriptions are claimed to be meant for Egypt’s nobility, and they are likely propaganda praising the famous pharaoh Ramesses II to be ordained by the divine entities. Apparently, the pharaoh himself commissioned this obelisk at the beginning of his rule, and it originally stood outside of the Luxor temple in upper Egypt alongside another similar obelisk. Both monuments were later gifted to France by Pasha Muhammed Ali, the sultan of the Ottoman Empire.a series of secret hieroglyphic inscriptions on an iconic 3300-year-old Egyptian obelisk in Paris.

Discovery of the hidden inscription

According to a comment published by Sciences et Avenir from Jean-Guillaume Olette-Pelletier, the Egyptologist from the Institut Catholique de Paris, the hieroglyphs indicated the entrance to the Luxor Temple portico. He discovered that there was no literature discussing the different scenes, so he studied the images from afar. He eventually discovered that the obelisk contained hieroglyphic cryptographies or hidden messages. These encrypted texts were often secret texts inserted into hieroglyphs or hidden in 3D carvings. Only the elite could decipher these hidden messages.

The hidden messages on the “Seine side” of the obelisk could only be read at a 45° angle. Olette-Pelletier discovered that the hidden messages were intended to be seen by nobles arriving by boat at the temple of Luxor during the annual Opet festival, celebrating the return of the life forces of the god Amun.

Further studies and criticism

According to Olette-Pelletier, he has discovered other concealed messages on the obelisk. He pointed out, for example, that there are two rows of hieroglyphs that, depending on how they are read, might convey several meanings, such as stating that Ramesses II had endless life or writing out his whole royal name.

The findings are set to be published in the journal Égypte Nilotique et Méditerranéenne. However, scholars who were not involved in the research have urged caution in interpreting the findings, as they will not be able to review them in depth until the study is published. Egyptology professor Filip Taterka told Live Science that the inscriptions and imagery near the top of the obelisk would not have been visible to a noble person traveling by boat on the Nile.

NASA’s New Space Telescope Starts Mapping to Reveal Universe’s Deep Mysteries

NASA’s SPHEREx space observatory has started capturing 3,600 distinct images every day as it maps the cosmos. Beginning with its launch on March 11, it will make more than 11,000 orbits over two years, circling Earth 14 and half times a day. The mission will produce four all-sky maps in two years, revealing clues into cosmic inflation and the expansion of the universe. The observatory will also map the entire sky in 102 infrared wavelengths of light, providing information about cosmic sources.

SPHEREx Telescope Exceeds Early Goals, Begins Mapping Universe in 3D Infrared Detail

As per a NASA Jet Propulsion Laboratory report, SPHEREx is already meeting performance expectations, rotating its orientation through reaction wheels rather than traditional thrusters. The telescope captures six different images, catching light in several infrared wavelengths with every exposure. Shawn Domagal-Goldman, acting head of NASA’s astrophysics division, underlined how the mission supports upcoming projects such as the Nancy Grace Roman Space Telescope. SPHEREx’s spinning view of the sky also allows it to cover the entire sky every six months and therefore conduct four complete surveys over its two-year lifetime.

SPHEREx will employ spectroscopy to measure the distance between galaxies, creating a 3D cosmic map and revealing how water on Earth came to be and the role interstellar clouds played in the creation of the chemicals necessary for life. It is aimed at more than nine million measurements of the Milky Way, revealing the influence of the environment on cosmic chemistry. As per mission principal investigator Jamie Bock, some team members have worked for over a decade toward this milestone, and the mission could exceed its original scientific goals.

NASA’s SPHEREx observations could show signs of cosmic inflation, which powered the expansion of the universe after the Big Bang. These tendencies could expose the structure and history of the universe as well as those of stars and galaxies. Headed by the Jet Propulsion Laboratory (JPL) of NASA at Caltech in the USA, SPHEREx is under a worldwide cooperation agreement comprising South Korea and Taiwan. Data analysis investigates the universe downward, closer.

Soviet Venus Probe Cosmos 482 Expected to Reenter Earth After 52 Years in Orbit

An Soviet Union lander is heading back into Earth’s atmosphere after 52 years staying in the orbit. Soviet Union’s Cosmos 482 was launched on March 31, 1972 and was supposed to land on Venus under the U.S.S.R.’s Venera programme. However, due to a certain malfunction, it could not leave Earth’s orbit and kept rotating around for 52 years. Its body was split into two halves; the main one crashed back to Earth, and the other section, the lander, got trapped in the Earth’s orbit.

Lander Returns to Earth

According to study, the lander is re-entering the Earth’s atmosphere and is expected to come back between May 8 to May 14. The most probable date is May 11, calculated based on the orbital data provided by satellite expert Marco Langbroek. This crash landing could occur anywhere between 52 degrees north and south of the equator, roughly from Quebec to Patagonia. According to NASA, the lander weighs around 1100 pounds, the weight of a car.

What Does it Look Like

This lander was designed to survive the way through the atmosphere of Venus, so there might be a possibility that it can survive the reentry into Earth’s atmosphere and remain intact with possibly no impact. However, the risks are not too high, but still not negligible, said Langbroek while speaking to Live Science.

Ralf Vandebergh, the advanced astrographer, used a camera attached to the telescope for tracking the orbiting satellites. Some images reveal that it might be the released parachute of the Cosmos 482, however, there is still no certainty, as it is surprising if the parachute will still work after so many years.

Cosmos 482 as Sister Probe to Venera 8

Cosmos 482 was built after Venera 8 as a sister probe. However, Venera 8 became the second craft to land on the hot surface of Venus during the same year, 1972. It beamed data from Venus for 50 minutes before getting burned by the scorching heat of Venus.
