Earth’s Quasi-Moon Finally Has A Name, Honoring The Roman Goddess Of... Hinges




One of Earth’s seven quasi-moons has just got a new name: Asteroid 2004 GU9 is now known as Cardea, one of the Roman deities of doors and thresholds with a particular focus on hinges.

Cardea is not a real satellite of our planet like the Moon  it is not gravitationally bound to the Earth, but it moves around the Sun in a way that makes it look like it goes around the Earth. It will continue to do so until well into the 2600s. There was a public call-out for name suggestions, and a panel of judges selected seven names. More than 10,000 people voted to select this name among the finalists, and Cardea was the winner.

“Cardea was the Roman goddess of the hinge. Roman doors hung on pivot hinges. Cardea was one of at least four Roman deities who presided over doorways. The name was selected by participants in the 2024 naming contest run by the WNYC (New York public radio) RadioLab program and the IAU,” the International Astronomical Union wrote in their latest Working Group Small Body Nomenclature bulletin.

Earth has seven known quasi-moons. Of those, only one had received an official name before this year: Kamoʻoalewa, which is believed to be a former piece of the Moon. Now that Cardea has been officially named, there might be an interest in naming the other five. Cardea is more than 160 meters (524 feet) in diameter, never getting closer to Earth than several tens of millions of kilometers.

The other final names from which Cardea was picked were the following:


Bakunawa – A mythical dragon from Philippine folklore said to rise from the ocean to swallow the Moon.

Ehaema – The Mother Twilight from Estonian Folklore, symbolizing the balance between light and dark.

Enkidu – The noble companion of Gilgamesh in the eponymous epic from Sumerian mythology.

Ótr – The shape-shifting dwarf of Norse mythology who spent his days in the form of an otter navigating the boundaries between the human realms and others.

Tarriaksuk – In Inuit legends, these are shadow beings that mirror human forms but dwell in other dimensions.

Tecciztecatl – An Aztec lunar god that once aspired to be Sun but a hesitant leap relegated him to the Moon.

Hopefully, they will be used for other celestial bodies, because they are absolutely excellent suggestions. The panel that selected the final seven names featured astrophysicists such as Dr Sofia Rojas, science communicators such as Bill Nye and Dr Moiya McTier, and actors such as Tony Award nominee Celia Rose Gooding (Uhura in Star Trek: Strange New Worlds) and Penn Badgley.

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Green comet to pass Earth, won't be back for another 50,000 years

   visit:  https://hep-conferences.sciencefather.com/ After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.   A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said. The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year. After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1. It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon. The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transi...
