Just as colors are made more dramatic in sunsets on Earth, sunsets on Mars, according to NASA, would appear bluish to human observers watching from the red planet. Fine dust makes the blue near the Sun's part of the sky much more visibilke, while normal daylight makes the Red Planet's familiar rusty dust color the most perceptible to the human eye.

55 Cancri e, also known as Janssen, orbits a star called Copernicus only 41 light years away. The molten surface is completely uninhabitable, but above the burning horizon, Janssen’s sister planet, Galileo, hangs in a dark sky. Silicates in the atmosphere would condense into clouds on the tidally-locked planet's darkside reflecting the lava below. So, the skies would sparkle.

There’s a planet made of diamonds twice the size of earth The "super earth," aka 55 Cancri e, is most likely covered in graphite and diamond. Paying a visit to that planet would probably pay for the $12 million dollar space suit needed to get there!

Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.

Between 2003 and 2004, NASA's Hubble Space Telescope spent more than 11 days taking what would become known as the Hubble Ultra Deep Field, a view of nearly 10,000 galaxies. In 2022, Webb took less than 24 hours to observe that same target in high-resolution.

Why are we revisiting this field? We don’t exactly know how galaxies became how they are today. With its sensitivity, Webb is helping astronomers hunt for the first galaxies and better understand star formation and other galactic properties in the early universe.

In addition, the Hubble Ultra Deep Field has long been studied by a variety of telescopes. Webb’s new data complements previous data sets by providing detailed information for just about all the galaxies in this field, providing scientists with new puzzle pieces they did not have before.

We love this with the fire of a trillion suns ❤️‍🔥

Shown here is Arp 220, an ultra-luminous infrared galaxy (ULIRG) with a luminosity literally greater than that of a trillion suns. (It emits 300 times more light than the Milky Way!) Arp 220 glows brightest in infrared light, Webb’s specialty.

This object is the result of a collision between 2 spiral galaxies that began about 700 million years ago, sparking a huge burst of star formation. The light from this star formation is shrouded in dust, which Webb can see through with its infrared vision. Located 250 million light-years away, Arp 220 is both the nearest ULIRG and the brightest of the 3 galactic mergers closest to us.

NASA's Hubble Space Telescope previously uncovered that the cores of the colliding galaxies are only about 1,200 light-years apart. Webb’s new view reveals material being drawn off the galaxies by gravity, shown in blue, as well as streams and filaments of coral-colored organic material.

While the entire suit costs a cool $12m, 70% of that cost is for the backpack and control module. However, the space suits that NASA uses were built in 1974. If these were priced by today's pricing, they would cost an estimated 150 million dollars!

The Sun is large enough that approximately 1.3 million Earths could fit inside (if squashed in) or if the Earths retained their spherical shape then 960,000 would fit. But can you visualise that number of Earths?
