In those 30 years, the sea level has risen by more than 9 centimeters. This may not seem like much, just a hand's length, but when these changes are visualized as water hitting a ship-like window, it starts to feel very real.

As the planet warms and polar ice melts, our global mean sea level is rising," NASA wrote.

NASA released this animation showing how much sea levels have risen from 1993 to 2022. "It gives you goosebumps to think of what's to come in the future"

Everything that is happening right now is right there on that little dot called Earth, as seen from the planet Mars.

If you had a giant swimming pool and put Saturn in it, it would float! Exactly, the ringed giant of the solar system has a density of 0.69 grams per cubic centimeter.

By comparison, water has a density of 1 gram per cubic centimeter. That way, being less dense, the planet would be able to float!

Jupiter, on the other hand, would sink. Its density is higher: 1.33 grams per cubic centimeter

The distance between the Earth and the Moon is 384,403 kilometers. All seven major planets in the solar system would fit in the space between the Earth and the Moon

Cosmic smoke & telescope mirrors?

Webb found complex organic molecules similar to smoke or smog in a galaxy more than 12 billion light-years from Earth. This sets a new record for the most distant detection of these big, complicated molecules.

The distant galaxy in question lies behind a much closer foreground galaxy. The gravity of the foreground galaxy is so great that it distorts and magnifies the light of the galaxy behind it, making it easier to see.

In space, where there’s smoke, there are stars — usually. But this galaxy might change astronomers’ long-held belief: These “smoky molecules” were abundant in some areas with little star formation, or were scarce in some areas with active star birth.

Due to how far light from this galaxy had to travel, we’re seeing this galaxy as it was back when the universe was < 1.5 billion years old. The discovery suggests that complex chemistry began occurring in the universe much earlier than we thought.

Remember those clouds that look like flying saucers? So they're called lenticular clouds and this time-lapse shows how they form over the Popocatepetl volcano in Mexico, these clouds always appear in relation to big mountains.

Meet the Belt of Venus, one of the countless proofs that the Earth is round and wonderful!!!

The molecule Webb discovered is called methyl cation (pronounced cat-eye-on). Carbon compounds are the foundation of life as we know it, and methyl cation (CH3+) plays an important role in forming more complex carbon-based molecules.

Here’s a closer look (bottom right) at the star system where methyl cation was found. Its planet-forming disk was bombarded with UV radiation from nearby young stars, radiation typically expected to destroy complex carbon molecules.

However, scientists believe the radiation may have been the source of energy necessary for methyl cation — and with it, more complex carbon molecules — to form. Understanding how UV radiation changes the chemistry of these disks could tell us more about the origins of life.

Webb — constantly raising the (Orion) Bar for us all.

While observing the Orion Bar, Webb made the first detection ever of a crucial carbon molecule in space. This molecule was found inside a planet-forming disk surrounding a young star system: https://go.nasa.gov/3NLiJyy

A refresher: TRAPPIST-1 c is the second planet from its star, the M dwarf TRAPPIST-1. M dwarf stars are intriguing because they are 10 times as common and 2 times more likely to have rocky planets than stars like our Sun. TRAPPIST-1 has seven!

Young M dwarf stars are energetic, emitting X-ray & UV radiation that can strip young planetary atmospheres away. It’s unknown if systems like these had water, carbon dioxide, or other ingredients to make atmospheres when the planets formed.

Webb is so sensitive that it can search for elements and molecules like oxygen, nitrogen, and carbon dioxide in exoplanet atmospheres. The mystery remains — can planets orbiting small M dwarfs sustain the atmospheres needed to support life as we know it?

TRAPPIST-1 b lacked atmosphere. TRAPPIST-1 c? Much the same. Though thought to be similar to Venus (both in size and amounts of radiation from its star), Webb found it lacks Venus’s thick CO2-rich atmosphere. If there is one, it’s very thin.

Roses, jellyfish, horses…

Hubble’s view of our universe includes cosmic images that remind us of the plants and animals right here on Earth!

This sonification was created by scientists to provide an auditory way of experiencing these images. While this isn’t the sound “of” space, sonifications represent data in the image to highlight certain scientific aspects through sound.

In this sonification, brightness controls volume & pitch, which means that the brightest sources in the image are the loudest & highest frequencies.

The X-rays from Chandra sound like a synthesizer, Spitzer’s infrared data are strings, and light from Hubble has bell-like tones.
