Venus

Venus is the brightest “star” in the cosmos. No wonder civilizations through the ages worshiped it.

In the whole universe, Venus may be the epitome of look-but-don’t-touch! And the air pressure is 90 times greater than Earth’s, so that you’d be peddling in the most deadly pressure cooker in the known universe. But the Evening Star — its other name — is actually slowly getting higher and brighter each evening as twilight fades. But if it reaches its greatest elongation in early spring, the plane of its orbit angles almost straight up from the sunset point. Venus is the brightest “star” in the cosmos. When it does appear in the evening sky, the nine month apparition’s visibility depends on the slant of its orbit with the horizon and how far from the blinding Sun it currently happens to be.

Venus is one of the brightest planet in the Solar System because if reflects 70% of sunlight back and is also the closest to Planet Earth.

As the Moon came in between Earth & Venus, the brightness of latter was expected to be curtailed by nearly 250 times. Though, the two planets are miles apart but as they align together in a symmetrical line, this makes it a puzzle for hundreds of thousands of curious skywatchers. New Delhi: The Solar system along with 9 planets and its numerous enigmas continue to puzzle the mankind.

While the heavenly bodies appear close to each other, their actual distance is millions of kilometres apart. Read more at straitstimes.com.

No, it’s the planet Venus – the brightest natural object that can be seen in the sky with the naked eye, apart from the sun and moon. The phenomenon is believed to herald the beginning of the astrological new year, and marks the time for resetting a new chapter in one’s life. Is the celestial orb a burning star?

Photos of the phenomenon by social media users were also shared in their comments sections, with many posting pictures from different states of the country. Photos on social media have been circulated, with many snapping away at the sight. On Twitter, the "Venus" topic has been listed as trending in Malaysia, with 69,000 tweets.

A team of researchers, including Brown planetary scientist Jim Head, propose using the James Webb Space Telescope to look at five planets in the Venus Zone, ...

Studying exoplanets in the Venus Zone could give astronomers a better understanding of whether Venus was ever habitable. The research team proposes the planets identified in the paper as targets for the Webb telescope in 2024. It is similar to the concept of a habitable zone, which is a region around a star where liquid surface water could exist. The Venus Zone encompasses the region around a star where it’s too hot for a planet to have water but not too hot for it to have no atmosphere. These terrestrial planets orbiting other stars, called exoplanets, were selected because they were the most likely to resemble Venus in terms of their radii, masses, densities, the shapes of their orbits and distances from their stars. Despite being such a scorching wasteland, however, the planet is often referred to as Earth’s sister because of similarities in size, mass, density and volume.

A.1. Geometrical projections of discontinuity events during 2022. This Supporting Figure displays the same examples of discontinuity as in Figure 1 but as ...

Ultraviolet images during 13-14 June 2022 suggest that the discontinuity may have manifested at the top of the clouds during ∼21 hours as a result of an altitude change in the critical level for this wave due to slower zonal winds. Taking advantage of the campaign of ground-based observations undertaken in coordination with the Akatsuki mission since December 2021 until July 2022, we aimed to undertake the longest uninterrupted monitoring of the cloud discontinuity up to date to obtain a pioneering long-term characterization of its main properties and better constrain its recurrence and lifetime. The discontinuity exhibited properties nearly identical to measurements in 2016 and 2020, with an orientation of 91∘±8∘, length/width of 4100±800 / 500±100 km and a rotation period of 5.11±0.09 days. Because winds gradually increase with height on Venus and have higher speeds than the discontinuity at the peak of the clouds, the discontinuity attempts to propagate upwards from the deep clouds, but meets this obstacle on its way and eventually dissipates. And if the winds grow much more slowly with height, the discontinuity takes longer to find atmospheric regions as fast as itself, allowing it to propagate to higher altitudes. It also happens on the Saturn moon Titan and on many exoplanets, but after more than half a century o research we still cannot satisfactorily explain it,” explains this researcher. “This is surprising, because until now the discontinuity appeared ‘trapped’ in the deepest clouds and we had never observed it at such a high altitude,” explains Peralta. In this vein, the Akatsuki images not only point to the fact that the discontinuity may have propagated to Venus’ upper clouds, but also help us to understand the reasons for this displacement. Hundreds of images were inspected in search of manifestations of the discontinuity events and to measure key properties like its dimensions, orientation or rotation period. The astrophysicist Javier Peralta was responsible for designing in 2022 the strategy for WISPR’s Venus observations during the spacecraft’s approach/departure manoeuvres during Parker’s flybys. “Measuring the winds on Venus is essential to try to explain why Venus’s atmosphere spins 60 times faster than the surface. The observations were carried out non-stop for more than 100 days.
