Vera C Rubin Observatory reveals its first spectacular images of the cosmos




The first spectacular images from the Vera C Rubin Observatory have been released today showing millions of galaxies and Milky Way stars and thousands of asteroids in exquisite detail.

Based in Cerro Pachón in the Andes, the Vera C Rubin Observatory contains the Legacy Survey of Space and Time (LSST) the largest camera ever built. Taking almost two decades to build, the 3200 megapixel instrument forms the heart of the observatory’s 8.4 m Simonyi Survey Telescope.

The image above is of the Trifid and Lagoon nebulas. This picture combines 678 separate images taken by the Vera C. Rubin Observatory in just over seven hours of observing time. It reveals otherwise faint or invisible details, such as the clouds of gas and dust that comprise the Trifid nebula (top right) and the Lagoon nebula, which are several thousand light-years away from Earth.

The image below is of the Virgo cluster. It shows a small section of the Virgo cluster, featuring two spiral galaxies (lower right), three merging galaxies (upper right) and several groups of distant galaxies.

Star mapper

Later this year, the Vera C Rubin Observatory, which is funded by the National Science Foundation and the Department of Energy’s Office of Science, will begin a decade-long survey of the southern hemisphere sky.

The LSST will take a complete picture of the southern night sky every 3-4 nights. It will then replicate this process over a decade to produce almost 1000 full images of sky.

This will be used to plot the positions and measure the brightness of objects in the sky to help improve our understanding of dark matter and dark energy. It will examine 20 billion galaxies as well as produce the most detailed star map of the Milky Way, imaging 17 billion stars and cataloguing some six million small objects within our solar system including asteroids.

Cosmic pioneer

The observatory is named in honour of the US astronomer Vera C. Rubin. In 1970, working with Kent Ford Jr, they observed that outer stars orbiting in the Andromeda galaxy were all doing so at the same speed.

Examining more galaxies still, they found that their rotation curves the orbital speed of visible stars within the galaxy compared with their radial distance to the galaxy centre contradicted Kepler’s law.

They also found that stars near the outer edges of the galaxies were orbiting so fast that they should be falling apart.

Rubin and Ford Jr’s observation led them to predict that there was some mass, dubbed “dark matter”, inside the galaxies responsible for the anomalous motions, something their telescopes couldn’t see but was there in quantities about six times the amount of the luminous matter present.

"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...
