This Is Cool Asf I Would Buy 98378593805 If I Wasn't Broke

A recently blinded man goes to a doctor and explains his issues to him. The doctor nods and says, "I see your problem." The blind man sighs and says, "Well I don't."

I see, I buy

I love how everyone thinks I'm innocent for not swearing and I laugh because they don't know about the string of endless demonic swears that constantly echo through my mind, like a million angry wasps at your window waiting to make you question who satan really is, at every vague discomfort that crosses me.

Sometimes… there’s more than meets the eye. 👀 You’re looking at two very different takes on an iconic image. ⁣

Human eyes can see only a small portion of the range of radiation given off by the objects around us. We call this wide array of radiation the electromagnetic spectrum, and the part we can see visible light.

In the first image, researchers revisited one of Hubble Space Telescope’s most popular sights: the Eagle Nebula’s Pillars of Creation. Here, the pillars are seen in infrared light, which pierces through obscuring dust and gas and unveil a more unfamiliar — but just as amazing — view of the pillars. ⁣ ⁣ The entire frame is peppered with bright stars and baby stars are revealed being formed within the pillars themselves. The image on the bottom is the pillars in visible light.

Cosmic Alphabet Soup: Classifying Stars

If you’ve spent much time stargazing, you may have noticed that while most stars look white, some are reddish or bluish. Their colors are more than just pretty – they tell us how hot the stars are. Studying their light in greater detail can tell us even more about what they’re like, including whether they have planets. Two women, Williamina Fleming and Annie Jump Cannon, created the system for classifying stars that we use today, and we’re building on their work to map out the universe.

By splitting starlight into spectra – detailed color patterns that often feature lots of dark lines – using a prism, astronomers can figure out a star’s temperature, how long it will burn, how massive it is, and even how big its habitable zone is. Our Sun’s spectrum looks like this:

Astronomers use spectra to categorize stars. Starting at the hottest and most massive, the star classes are O, B, A, F, G (like our Sun), K, M. Sounds like cosmic alphabet soup! But the letters aren’t just random – they largely stem from the work of two famous female astronomers.

Williamina Fleming, who worked as one of the famous “human computers” at the Harvard College Observatory starting in 1879, came up with a way to classify stars into 17 different types (categorized alphabetically A-Q) based on how strong the dark lines in their spectra were. She eventually classified more than 10,000 stars and discovered hundreds of cosmic objects!

That was back before they knew what caused the dark lines in spectra. Soon astronomers discovered that they’re linked to a star’s temperature. Using this newfound knowledge, Annie Jump Cannon – one of Fleming’s protégés – rearranged and simplified stellar classification to include just seven categories (O, B, A, F, G, K, M), ordered from highest to lowest temperature. She also classified more than 350,000 stars!

Type O stars are both the hottest and most massive in the new classification system. These giants can be a thousand times bigger than the Sun! Their lifespans are also around 1,000 times shorter than our Sun’s. They burn through their fuel so fast that they only live for around 10 million years. That’s part of the reason they only make up a tiny fraction of all the stars in the galaxy – they don’t stick around for very long.

As we move down the list from O to M, stars become progressively smaller, cooler, redder, and more common. Their habitable zones also shrink because the stars aren’t putting out as much energy. The plus side is that the tiniest stars can live for a really long time – around 100 billion years – because they burn through their fuel so slowly.

Astronomers can also learn about exoplanets – worlds that orbit other stars – by studying starlight. When a planet crosses in front of its host star, different kinds of molecules in the planet’s atmosphere absorb certain wavelengths of light.

By spreading the star’s light into a spectrum, astronomers can see which wavelengths have been absorbed to determine the exoplanet atmosphere’s chemical makeup. Our James Webb Space Telescope will use this method to try to find and study atmospheres around Earth-sized exoplanets – something that has never been done before.

Our upcoming Nancy Grace Roman Space Telescope will study the spectra from entire galaxies to build a 3D map of the cosmos. As light travels through our expanding universe, it stretches and its spectral lines shift toward longer, redder wavelengths. The longer light travels before reaching us, the redder it becomes. Roman will be able to see so far back that we could glimpse some of the first stars and galaxies that ever formed.

There is no difference between a white man and a black man; only fools would see them as apart. Even Satan was once honored among angels. I will not stand here, having suffered ultimate rebellion by being kind in a cruel world and have you tell me I am defined by your mercurial views that are who I am not and never will be. I believe people are people. Humans will be humans. Our own cowardly insecurities lead to belittling those who are capable of greatness. Only the inferior fear those who aren’t.

the good old days..

So whenever I wake up in the morning I have very muddled and foggy thoughts that can range from me thinking about why the floor is higher than usual to talking to my wall.

Anyways, I woke up extra early today and went to the bathroom. I was going to wash my face so I turned on the tap and put my hand beneath and it was COLD like really really extremely ultra pro max cold so I immediately pulled my hand away and the first thought that came to my mind was:

Damn,

I just recoiled like a brick

tears drip from your eyes, streaming down your face and I call the plumber because there seems to be a leak

he will know what to do.
