“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth,” says Professor Anders Johansen. Credit: NASA, ESA and G. Bacon (STScI)
Now, researchers from the GLOBE Institute at the University of Copenhagen have published an eye-opening study, indicating that water may be present during the very formation of a planet. According to the study’s calculations, this is true for both Earth, Venus and Mars.
In case you are keeping track:
Are there any more planets like Earth in the Milky Way galaxy?
So far, it has been assumed that water is available on the planets via a chance collision with an ice asteroid. However, experts have come up with a new theory stating that water may be present initially when planets were formed, as in the case of Venus, Mars and Earth. The data collected by researchers has pointed out that water has been more like one of the building blocks for Earth.
New method for finding Earth-like planets | Mirage News
The Very Large Telescope (VLT) at Paranal Observatory in Chile’s Atacama Desert. New research adapts instrumentation to enable the search for planets in other solar systems.

A new technique for reducing light interference during telescope observations enables imaging of earth-like planets in nearby solar systems. An international team of astronomers and physicists, including researchers from Uppsala University, have used a diamond coronagraph to look for planets in the solar system Alfa Centauri, just 4.4 light years away. The method has demonstrated promising results.
Cool Pics. from the Planet Jupiter | WOODTV.com
The NASA Spacecraft Juno is sending back some nifty pictures of the planet Jupiter. Jupiter is by far the biggest planet in our solar system, with a mass 2 1/2 times the size of all the other planets combined. It’s the 3rd brightest object in the night sky, after the moon and Venus.
The pic. above looks like an entry from Art Prize. Jupiter has a planet-wide cloud cover. The clouds are made up of ammonia crystals. The cloud layer is approx. 31 miles thick and wind speeds of over 200 occur in zonal jet streams. Flashes of light have been seen from the top of the cloud layer.

These are more than rocky bodies orbiting the sun. Planets have to fulfill three criteria. First, they have to orbit a star in a predictable way. In our solar system, that star is the sun. Planets orbiting other stars are also called exoplanets .
Second, planets have to be big enough to have enough gravity to force them into a round shape. Finally, a planet also needs to have enough gravity to keep other objects — such as asteroids — out of its path around its star. In other words, planets are selfish — they don’t share their orbit with any other objects.
Watch how Frontier is remaking the planets for Elite Dangerous: Odyssey
In the spring , players will finally have the opportunity to explore planets in Elite Dangerous: Odyssey . And it is not going to be one or two planets. The expansion will bring a whole galaxy’s worth of planets to the game. In preparation for the sheer amount of landings and exploration, Frontier Developments is doing some brilliant work. This means rebuilding all of the current planets found in the game, as well as adding many new ones for Elite Dangerous: Odyssey .
Blast Off: Experiencing Seasons on Different Planets
Spring starts next month on Earth, but winter can last for years on other planets in the solar system.
With the successful landing of NASA's Perseverance on Mars , you may be thinking a little bit more about other planets these days.
Did you know seasonal changes aren't something unique to earth? However, they can be vastly different between planets.
Planetary seasons are determined by axial tilt and and its distance from the sun. Take Earth for example.

A new theory that may explain why the inner solar system is so different to the outer regions runs counter to the prevailing wisdom.
Mercury, Venus, Earth, and Mars in the inner solar system are relatively small, dry planets, unlike Jupiter, Saturn, Uranus, and Neptune in the outer regions, planets that contain much greater quantities of volatile elements.
“In the last few years, we’ve also discovered another major difference between the two parts of the solar system,” says Maria Schönbächler, professor at the Institute of Geochemistry and Petrology at ETH Zurich. “Meteorites have a different ‘fingerprint’ depending on whether they originated in the inner or the outer solar system.” Where they originate determines the meteorites’ isotope content.
