NASA’s Webb Space Telescope Reveals Astounding, Unprecedented Views of the Universe
Can I just say that as a future engineer, and hopeful candidate for the NASA space program Katherine Johnson, and NASA engineer Mary Jackson are the women I look up to. Every day I go to class I get my male peers treating me like I do f have the capability to understand the coursework. I get declined internships because they don’t feel I could handle the workload like the “strong men on the floor.” However none of these small inconveniences even pale in comparison to the suffering these brave, brilliant women had to go through to garner the respect they so deserved. Despite all the hardship, injustice, prejudice, and hate they received from a society who refused to see their worth simply because of what they looked like, these women kept fighting. They fought the good fight, and helped pave the way to a better future. A future where men and women alike could touch the stars. These are the women I want to make proud. These are the women that I want to succeed for.
Katherine Johnson (b. 1918) is a physicist and mathematician who has made crucial contributions to several NASA missions, assuring their success with her highly accurate calculations. She worked with NASA for several decades, and helped advance the rights of both African-Americans and women.
She initially worked as a human computer, and later as an aerospace technologist. She calculated trajectories for missions such as the 1961 Mercury mission or the 1969 Apollo 11 flight. She was portrayed by Taraji P. Henson in the 2016 film Hidden Figures.
Getting a t-shirt with this print A.S.A.P.!
According to an index developed in 2015, the Earth is not the most habitable planet discovered in the Universe. Kepler-442b, a rocky exoplanet 1,206 light years from Earth, has a rating of 0.836. Earth is at 0.829.

Mars Rovers (plus little helicopter Ingenuity)
I recently saw a few things about robotics and how we treat them both in the real world and in fiction, along with the fact we named the Mars Rovers.
Sure, robots are programmed and can't "feel" in a typical way, but not all humans can process things all the same either. So why deny that our creations can't feel either? Opportunity's last message makes me weep every time I look at it.
For now, I hope all our little robot companions up on Mars can eventually come home.
May the Four Forces Be With You!
May the force be with you? Much to learn you still have, padawan. In our universe it would be more appropriate to say, “May the four forces be with you.”
There are four fundamental forces that bind our universe and its building blocks together. Two of them are easy to spot — gravity keeps your feet on the ground while electromagnetism keeps your devices running. The other two are a little harder to see directly in everyday life, but without them, our universe would look a lot different!
Let’s explore these forces in a little more detail.
Gravity: Bringing the universe together
If you jump up, gravity brings you back down to Earth. It also keeps the solar system together … and our galaxy, and our local group of galaxies and our supercluster of galaxies.
Gravity pulls everything together. Everything, from the bright centers of the universe to the planets farthest from them. In fact, you (yes, you!) even exert a gravitational force on a galaxy far, far away. A tiny gravitational force, but a force nonetheless.

Despite its well-known reputation, gravity is actually the weakest of the four forces. Its strength increases with the mass of the two objects involved. And its range is infinite, but the strength drops off as the square of the distance. If you and a friend measured your gravitational tug on each other and then doubled the distance between you, your new gravitational attraction would just be a quarter of what it was. So, you have to be really close together, or really big, or both, to exert a lot of gravity.
Even so, because its range is infinite, gravity is responsible for the formation of the largest structures in our universe! Planetary systems, galaxies and clusters of galaxies all formed because gravity brought them together.
Gravity truly surrounds us and binds us together.
Electromagnetism: Lighting the way
You know that shock you get on a dry day after shuffling across the carpet? The electricity that powers your television? The light that illuminates your room on a dark night? Those are all the work of electromagnetism. As the name implies, electromagnetism is the force that includes both electricity and magnetism.
Electromagnetism keeps electrons orbiting the nucleus at the center of atoms and allows chemical compounds to form (you know, the stuff that makes up us and everything around us). Electromagnetic waves are also known as light. Once started, an electromagnetic wave will travel at the speed of light until it interacts with something (like your eye) — so it will be there to light up the dark places.
Like gravity, electromagnetism works at infinite distances. And, also like gravity, the electromagnetic force between two objects falls as the square of their distance. However, unlike gravity, electromagnetism doesn’t just attract. Whether it attracts or repels depends on the electric charge of the objects involved. Two negative charges or two positive charges repel each other; one of each, and they attract each other. Plus. Minus. A balance.
This is what happens with common household magnets. If you hold them with the same “poles” together, they resist each other. On the other hand, if you hold a magnet with opposite poles together — snap! — they’ll attract each other.
Electromagnetism might just explain the relationship between a certain scruffy-looking nerf-herder and a princess.
Strong Force: Building the building blocks

The strong force is where things get really small. So small, that you can’t see it at work directly. But don’t let your eyes deceive you. Despite acting only on short distances, the strong force holds together the building blocks of the atoms, which are, in turn, the building blocks of everything we see around us.
Like gravity, the strong force always attracts, but that’s really where their similarities end. As the name implies, the force is strong with the strong force. It is the strongest of the four forces. It brings together protons and neutrons to form the nucleus of atoms — it has to be stronger than electromagnetism to do it, since all those protons are positively charged. But not only that, the strong force holds together the quarks — even tinier particles — to form those very protons and neutrons.
However, the strong force only works on very, very, very small distances. How small? About the scale of a medium-sized atom’s nucleus. For those of you who like the numbers, that’s about 10-15 meters, or 0.000000000000001 meters. That’s about a hundred billion times smaller than the width of a human hair! Whew.
Its tiny scale is why you don’t directly see the strong force in your day-to-day life. Judge a force by its physical size, do you?
Weak Force: Keeping us in sunshine
If you thought it was hard to see the strong force, the weak force works on even smaller scales — 1,000 times smaller. But it, too, is extremely important for life as we know it. In fact, the weak force plays a key role in keeping our Sun shining.
But what does the weak force do? Well … that requires getting a little into the weeds of particle physics. Here goes nothing! We mentioned quarks earlier — these are tiny particles that, among other things, make up protons and neutrons. There are six types of quarks, but the two that make up protons and neutrons are called up and down quarks. The weak force changes one quark type into another. This causes neutrons to decay into protons (or the other way around) while releasing electrons and ghostly particles called neutrinos.
So for example, the weak force can turn a down quark in a neutron into an up quark, which will turn that neutron into a proton. If that neutron is in an atom’s nucleus, the electric charge of the nucleus changes. That tiny change turns the atom into a different element! Such reactions are happening all the time in our Sun, giving it the energy to shine.
The weak force might just help to keep you in the (sun)light.
All four of these forces run strong in the universe. They flow between all things and keep our universe in balance. Without them, we’d be doomed. But these forces will be with you. Always.

HiPOD: Layered Deposits in Uzboi Vallis
Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it. These deposits may record deposition into a large lake that once filled Uzboi Vallis when it was temporarily dammed at its northern end by the rim of Holden Crater and before it was overtopped and breached allowing water to drain back out of the valley.
Layered deposits similar to those here may remain preserved where they were protected from erosion during drainage of the lake. Data from the CRISM instrument onboard MRO shows that clays are within these deposits that may differ from clays found elsewhere on the valley floor. Hence, the clays in these layers may have been washed into the lake from surrounding clay-bearing surfaces. (Enhanced color cutout is less than 1 km across.)

your bio promises space facts. i request a space fact 👀
Shout out to anon for calling me out on the fact that I have not been posting enough space facts, I must remedy that.
Sometime in the near future(I'm talking next few months near) in febuary of this year the hubble telescope took a picture of the IC 3476 dwarf galaxy undergoing a process called ram pressure stripping which compresses the star firing gasses which can often lead to the hindrance of star formation. However, in IC 3476 this process actually boosts star formation deep in the galaxy since most of the ram pressure stripping is towards the outer edge of the galaxy.
Daily space post lasted for 2 days bc I'm busy, so get ready for...
✨️sometimes regular space posts✨️
Nasa recently used two different telescopes to discover that what was previously believed to be one star in the WL20 star system is actually two twin stars. They discovered this because they found two distinguished disc with parallel jets of light erupting from around the stars.
🌌Space Facts!🌌
The galexy known as SDSS1335+0728 began emitting light indicative of an active black hole consuming gas. However, it remained illuminated for years while most only remain alight for a few weeks! Scientists observed this phenomenon closely, and we're able to view the awakening of a black hole for the first time!
🚀Space Facts!🚀
The black hole at the center of a galaxy act like the "heat and lungs" of the galaxy by controlling how much gas the galaxy absorbs to form stars.
Without this mechanism galaxies would expand to quickly causing it to age faster leaving a "zombie galaxy" filled with dead and dying stars
🪐Space Facts!🪐
NASA's Curiosity rover found a field of pure sulfur, whereas most other sulfur found has been a mix of sulfur and some other mineral. Scientist compared this to an oasis in the desert!
Due to the environment on Mars, this sulfur is odorless since the odor is caused by hydrogen sulfide gas
