Did Saturn, the Lord of the Rings, lose his crown?

Exoplanet J1407b has rings so big it makes Saturn look like a dwarf planet!

The planet Saturn may even be the Lord of the Rings of the Solar System, but its title certainly does not have the same power if we consider the entire Universe.

Astronomers have noticed the repeated and prolonged dimming of a star similar to the Sun, and according to interpretations and observational experiences, this indicates an eclipse passing through a complex and giant planetary ring, similar to the rings of Saturn, but much, much larger. Furthermore, the different densities of these rings imply the presence of at least one large exomoon, and perhaps one more in the process of formation.

J1407 is a main-sequence orange dwarf star located about 116 light-years away. Over the course of 57 days in 2007, the star J1407 underwent a "complex series of eclipses", which an international team of astronomers claims is the result of a system of rings around an exoplanet known as J1407b.

"This planet is much larger than Jupiter or Saturn, and its ring system is about 200 times the size of Saturn's rings," and we can imagine it as a super-Saturn."

J1407b's dense rings span about 180 million kilometers, and may have the same mass as Earth.

"If we could replace Saturn's rings with J1407b's rings, they would be easily visible at night, and they would be much larger than the Full Moon."

Planet J1407b has a mass up to 40 times that of Jupiter, and technically, it could be a brown dwarf.

his is what the Himalayas look like from space. 🏔️

The Himalayas, or Himalaya is a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has many of Earth's highest peaks, including the highest, Mount Everest, at the border between Nepal and China. The Himalayas include over fifty mountains exceeding 7,200 m (23,600 ft) in elevation, including ten of the fourteen 8,000-metre peaks. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is 6,961 m (22,838 ft) tall.

This Day In Science History ---

On this day: 25 August 1609, made the first recorded demonstration of an early , with a magnification of about 8 or 9, to Venetian lawmakers. Based on rough descriptions of the first practical telescope (which tried to patent in the Netherlands in 1608), Galileo had made a telescope with about 3x magnification. He later improved this with versions with up to about 30x magnification. By in March 1610, he had published his first astronomical observations by telescope in a paper called .

SPECTACULAR IMAGE OF THE SUN

This beautiful photograph was taken by Alan Friedman, an amateur astronomy photographer, but it almost looks like it was taken by a NASA space probe. Friedman actually takes them from the backyard of his home in Buffalo (New York) with a telescope and special filters so as not to damage the equipment. The raw images are in black and white and in high definition, but Friedman applies color and contrast to them to bring out certain aspects of the solar surface. The result is frankly spectacular.

Friedman uses an alpha hydrogen filter that lets in only the light needed to capture these images. It connects it to a telescope that would be equivalent to a 450mm f/5 telephoto lens and uses a we**am to capture the photos (the we**am can send images at a rate of 15 to 120 frames per second).

COMET ATLAS • Doomed Celestial Visitor May Have been a Piece of a Prehistoric Comet
20.8.2021

IMAGE: Comet C/2019 Y4 (ATLAS), taken on April 20 2020, reveals the breakup of the solid nucleus of the comet. Hubble photos identify as many as 30 separate fragments. The comet was approximately 91 million miles from Earth when the images were taken. The comet may be a broken off piece of a larger comet that swung by the Sun 5,000 years ago. The comet has been artificially colored in this view to enhance details for analysis. Credits: NASA, ESA, Quanzhi Ye (UMD). Image Processing: Alyssa Pagan (STScI)

• When our very early ancestors were colonizing the Nile River Valley, 5,000 years ago at the dawn of civilization, it's likely a brilliant comet appeared in the predawn sky. There is no direct evidence for this visitor because the start of recorded history was still a few centuries away.

The belief is that comet at least split into two pieces, which would not return to the Sun along the same orbital track until 5,000 years later. This forensic evidence can be linked to the great comet of 1844 that was nearly as bright as the brightest naked-eye star, Sirius. The second fragment, called comet ATLAS, appeared near the beginning of 2020.

Unlike its sibling that survived passing around the Sun in 1844, ATLAS met an untimely death while it was still 100 million miles from the Sun. It completely disintegrated as photographed by the Hubble Space Telescope.

A star forms through the gravitational collapse of a cloud of gas that is highly compressed. In other words, there are clouds of gas (with great abundance of hydrogen) that start to gather more and more. As the cloud grows, the material in the center begins to heat up, until hydrogen atoms begin to fuse into new elements. This process generates light and heat that we observe in stars.

Gravitational collapse is compensated by the pressure force exerted by nuclear fusion. Thus, a giant ball of very hot gas is stable for billions of years.
