Scientists have pinpointed what they say is one of the “most extreme planets” ever discovered on the edges of our solar system . How extreme, you ask? Well, its oceans are made of molten lava to start. Oh, and it also rains rocks and has supersonic winds.
“The study is the first to make predictions about weather conditions on K2-141b that can be detected from hundreds of light-years away with next-generation telescopes such as the James Webb Space Telescope,” Giang Nguyen, a PhD student at York University, and lead author of the study, said .

Indian poet-diplomat's anthems on planets of the solar system may amaze you - it s viral -
Indian poet-diplomat Abhay K has penned anthems on all the planets of the solar system on the occasion of the 86th birth anniversary of Carl Sagan, the globally renowned astronomer and planetary scientist.
Abhay wrote the Earth Anthem in 2008 which was put to music in 2013. He wrote Moon Anthem in 2019 to mark the landing of Chandrayan-2 on the moon and later Mars Anthem in early 2020.
Renowned violinist Dr L Subramaniam has composed music for Earth Anthem and Moon Anthem and Kavita Krishnamurti has sung them, while the Kenyan artist ONDIKO Kevin has composed music for Mars Anthem and Kapnea has sung it.
Every planet in our Solar System will be visible this week — here's how to spot them
All the planets in the Solar System are visible in the night sky this week, making a beautiful sight for stargazers. Even the outermost planets — Uranus, and Neptune (plus the dwarf planet Pluto) can be seen by observers using telescopes.
Jupiter and Saturn can easily be found in the southwestern region of the evening skies, while everyone's favorite ex-planet, Pluto, can be found by skilled amateur astronomers. Venus and Mercury, huddling close to the Sun, can be seen just before sunrise. Mars, meanwhile, is spending its time with our two ice giants — Uranus and Neptune.

In a new study researchers, led by Research Scientist Dimitra Atri of the Center for Space Science at NYU Abu Dhabi (NYUAD), identified which stars were most likely to host habitable exoplanets based on the calculated erosion rates of the planetary atmospheres.
How To See 5 Planets In The Night Sky In November - Simplemost
Longer nights, drier weather and clear skies during the fall months create the perfect conditions for viewing the night sky .

Close observers will be able to get a look at five different planets — without needing a telescope.
The five planets sky watchers will able to spot are Earth’s closest neighbors: Mercury, Venus, Mars, Jupiter and Saturn.
Mars, Jupiter and Saturn will be visible right at dusk and early nightfall. You’ll have to be more patient to see Mercury and Venus, because they don’t show up until the early morning hours.
Ask Astro: Can planets be pear-shaped, or are they all spheres? | Astronomy.com
A:Bodies large enough to be considered planets have enough mass that gravity molds them into a roughly spherical shape. The key word here is roughly — other factors also come into play, such as a planet’s composition (rocky or gassy) and its rate of spin. The faster a planet spins, the more its rotation causes it to bulge outward at the equator.
* * *
The gas giants Jupiter and Saturn bulge outward the most — Jupiter is nearly 7 percent thicker at its equator than its poles, and Saturn is 10.7 percent thicker around the middle. Ice giants Uranus and Neptune have smaller central bulges, only 2.3 percent and 1.7 percent thicker at the equator, respectively.
Water may be naturally occurring on all rocky planets -- ScienceDaily
"There are two hypotheses about the emergence of water. One is that it arrives on planets by accident, when asteroids containing water collide with the planet in question," says Professor Martin Bizzarro from the Centre for Star and Planet Formation at the Faculty of Health and Medical Sciences, University of Copenhagen.
Together with Assistant Professor Zhengbin Deng he has headed a new study that turns the theory about the emergence of water upside down.
