Ask the Weather Guys: Is there snow and ice on other planets?

Becky Williams, science researcher with the Mars rover Curiosity project, examines imagery captured on the surface of the planet on a computer screen in the work office of her Waunakee, Wis., home.

A: Like Earth, the north and south poles of Mars have ice caps that grow and shrink with Mars' seasons.

Webb's study of planet-forming disk hints at future exoplanet discoveries | Space

The James Webb Space Telescope has for the first time peered inside a planet-forming disk of dust surrounding a nearby star, a development promising to supercharge the search for exoplanets. 

Using the James Webb Space Telescope 's near-infrared camera ( NIRCam ), a team of astronomers led by Kellen Lawson, a postdoctoral program fellow at NASA Goddard Space Flight Center, observed the surroundings of a red dwarf star known as AU Microscopii or AU Mic.

It's official: NASA has discovered another planet just like Earth

Billionaire Elon Musk wants humanity to inhabit other planets like earth by 2050, with Mars currently being on his radar.

While we lack the foresight to properly answer that question, we do know one thing – the rapid advancements in technology give us hope about the limitless possibilities of what humanity can achieve. Case in point…

Mantle mineralogy limits to rocky planet water inventories | Monthly Notices of the Royal ...

Claire Marie Guimond, Oliver Shorttle, John F Rudge, Mantle mineralogy limits to rocky planet water inventories, Monthly Notices of the Royal Astronomical Society , 2023;, stad148, https://doi.org/10.1093/mnras/stad148

Nominally anhydrous minerals in rocky planet mantles can sequester multiple Earth-oceans' worth of water. Mantle water storage capacities therefore provide an important constraint on planet water inventories.

Does Planet X really exist? | Daily Mail Online

It has been six years since astronomers found strong evidence that a mysterious ninth planet might exist at the far reaches of our solar system .

If it is real, scientists say it could have a mass about 10 times that of Earth and may take between 10,000 and 20,000 years to make one full orbit around the sun.

Astronomers try to crack mystery of ice planets Uranus and Neptune

Writer and astronomer Carolyn Kennett tells Laura Smith the Honest Truth about these ice giants, from their discovery, surfaces and orbits to their multiple moons and future exploration

The discovery came off the back of a communication with Urbain Le Verrier, the director of the Paris Observatory who had mathematically predicted the planet's position and had told them where to turn their scopes.

Western Slope Skies: Mars with the Naked Eye

One way to tell the difference between a planet and a star is to study its light. The
light of nearby planets, like Mars and Venus, covers a larger area of the sky than
the stars.

This wandering is easy to see for yourself. Right now, Mars is just a little north of
the bright star Aldebaran, part of the constellation Taurus. Coincidentally,
Aldebaran also has a reddish hue.

Space discoveries that will blow your mind | KRQE News 13

(STACKER) – Since NASA’s inception in 1958, astronauts have landed on the moon; parked rovers on Mars; discovered thousands of exoplanets—planets that orbit stars outside of this solar system; and launched a space telescope so powerful it can capture detailed views of ...

The size of the universe is hard to fathom, and it’s expanding even faster than scientists originally thought. While humans will likely never map out the entirety of space, that doesn’t stop them from exploring it.
