SPACE MENTION 🌌🗣

Astronomers used three of NASA's Great Observatories to capture this multiwavelength image showing galaxy cluster IDCS J1426.5+3508. It includes X-rays recorded by the Chandra X-ray Observatory in blue, visible light observed by the Hubble Space Telescope in green, and infrared light from the Spitzer Space Telescope in red. This rare galaxy cluster has important implications for understanding how these megastructures formed and evolved early in the universe.

How Astronomers Time Travel

Let’s add another item to your travel bucket list: the early universe! You don’t need the type of time machine you see in sci-fi movies, and you don’t have to worry about getting trapped in the past. You don’t even need to leave the comfort of your home! All you need is a powerful space-based telescope.

But let’s start small and work our way up to the farthest reaches of space. We’ll explain how it all works along the way.

This animation shows a small, blue planet Earth at the left of the frame and an even smaller white dot representing the Moon at the right. The background is black. A beam of light travels back and forth between them. The graphic is labeled “Earth and Moon to scale, Speed of light in real-time, surface-to-surface in 1.255 seconds, average distance 384,400 km.” Credit: James O'Donoghue, used with permission

This animation illustrates how fast light travels between Earth and the Moon. The farther light has to travel, the more noticeable its speed limit becomes.

The speed of light is superfast, but it isn’t infinite. It travels at about 186,000 miles (300 million meters) per second. That means that it takes time for the light from any object to reach our eyes. The farther it is, the more time it takes.

You can see nearby things basically in real time because the light travel time isn’t long enough to make a difference. Even if an object is 100 miles (161 kilometers) away, it takes just 0.0005 seconds for light to travel that far. But on astronomical scales, the effects become noticeable.

The Sun and planets are lined up along the center of the frame with distances shown to scale. The title is “The Solar System: with real-time speed of light.” Earth is labeled 1 AU, 8 minutes 17 seconds; Jupiter is 5.2 AU, 43 minutes 17 seconds; Saturn is 9.6 AU, 1 hour 20 minutes; Uranus is 19.2 AU, 2 hours 40 minutes; and Neptune is 30 AU, 4 hours 10 minutes. The bottom of the graphic says, “1 AU (astronomical unit) = 93 million miles, or 150 million kilometers.” Credit: James O'Donoghue, used with permission

This infographic shows how long it takes light to travel to different planets in our solar system.

Within our solar system, light’s speed limit means it can take a while to communicate back and forth between spacecraft and ground stations on Earth. We see the Moon, Sun, and planets as they were slightly in the past, but it's not usually far enough back to be scientifically interesting.

As we peer farther out into our galaxy, we use light-years to talk about distances. Smaller units like miles or kilometers would be too overwhelming and we’d lose a sense of their meaning. One light-year – the distance light travels in a year – is nearly 6 trillion miles (9.5 trillion kilometers). And that’s just a tiny baby step into the cosmos.

The Sun’s closest neighboring star, Proxima Centauri, is 4.2 light-years away. That means we see it as it was about four years ago. Betelgeuse, a more distant (and more volatile) stellar neighbor, is around 700 light-years away. Because of light’s lag time, astronomers don’t know for sure whether this supergiant star is still there! It may have already blasted itself apart in a supernova explosion – but it probably has another 10,000 years or more to go.

What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, this image reveals previously obscured areas of star birth.

The Carina Nebula clocks in at 7,500 light-years away, which means the light we receive from it today began its journey about 3,000 years before the pyramids of Giza in Egypt were built! Many new stars there have undoubtedly been born by now, but their light may not reach Earth for thousands of years.

Glowing spiral arms are twisted around like a cosmic cinnamon roll. A bright yellow oval is diagonal in the center of the frame, and sprays of stars extend outward from it like tentacles. Pink, white, and blue stars speckle the spiral arms and dusty lanes lie in between. The glowing arms are streaked with smaller clumps of dust. Credit: NASA and Nick Risinger

If we zoom way out, you can see that 7,500 light-years away is still pretty much within our neighborhood. Let’s look further back in time…

Vaguely purplish swirling arms extend outward from the center and appear somewhat mottled as streams of dust block white and blue stars in the arms here and there. A few stars are each surrounded by many sharp diffraction spikes. Credit: ESA/Hubble and NASA, A. Riess et al.; acknowledgement: Mahdi Zamani

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643. Looking this good isn’t easy; 30 different exposures, for a total of nine hours of observation time, together with Hubble’s high resolution and clarity, were needed to produce an image of such exquisite detail and beauty.

Peering outside our Milky Way galaxy transports us much further into the past. The Andromeda galaxy, our nearest large galactic neighbor, is about 2.5 million light-years away. And that’s still pretty close, as far as the universe goes. The image above shows the spiral galaxy NGC 5643, which is about 60 million light-years away! That means we see it as it was about 60 million years ago.

As telescopes look deeper into the universe, they capture snapshots in time from different cosmic eras. Astronomers can stitch those snapshots together to unravel things like galaxy evolution. The closest ones are more mature; we see them nearly as they truly are in the present day because their light doesn’t have to travel as far to reach us. We can’t rewind those galaxies (or our own), but we can get clues about how they likely developed. Looking at galaxies that are farther and farther away means seeing these star cities in ever earlier stages of development.

The farthest galaxies we can see are both old and young. They’re billions of years old now, and the light we receive from them is ancient since it took so long to traverse the cosmos. But since their light was emitted when the galaxies were young, it gives us a view of their infancy.

The animation begins with a tiny dot of purplish light which quickly explodes, with a flash of light blossoming out to cover the whole frame. The light subsides and the screen shows galaxies of smudgy or spiral shapes racing outward from the center of the frame. Credit: NASA’s Goddard Space Flight Center

This animation is an artist’s concept of the big bang, with representations of the early universe and its expansion.

Comparing how fast objects at different distances are moving away opened up the biggest mystery in modern astronomy: cosmic acceleration. The universe was already expanding as a result of the big bang, but astronomers expected it to slow down over time. Instead, it’s speeding up!

The universe’s expansion makes it tricky to talk about the distances of the farthest objects. We often use lookback time, which is the amount of time it took for an object’s light to reach us. That’s simpler than using a literal distance, because an object that was 10 billion light-years away when it emitted the light we received from it would actually be more than 16 billion light-years away right now, due to the expansion of space. We can even see objects that are presently over 30 billion light-years from Earth, even though the universe is only about 14 billion years old.

Hundreds of red, yellow, white, and blue galaxies are sprinkled across a black background, appearing as small, brightly colored smudges. The tiniest galaxies appear as mere dots, while larger ones are disk-shaped. One blue star with six diffraction spikes shines in the lower-left corner. Credit: NASA, ESA, CSA, and M. Zamani (ESA/Webb). Science: B. Robertson (UCSC), S. Tacchella (Cambridge), E. Curtis-Lake (Hertfordshire), S. Carniani (Scuola Normale Superiore), and the JADES Collaboration

This James Webb Space Telescope image shines with the light from galaxies that are more than 13.4 billion years old, dating back to less than 400 million years after the big bang.

Our James Webb Space Telescope has helped us time travel back more than 13.4 billion years, to when the universe was less than 400 million years old. When our Nancy Grace Roman Space Telescope launches in a few years, astronomers will pair its vast view of space with Webb’s zooming capabilities to study the early universe in better ways than ever before. And don’t worry – these telescopes will make plenty of pit stops along the way at other exciting cosmic destinations across space and time.

Learn more about the exciting science Roman will investigate on X and Facebook.

SPACE RAHHH🗣🗣‼️‼️‼️‼️🗣🗣

An illustration showing the planet Jupiter rising over the horizon of its moon Europa. Europa’s surface consists of a rough landscape of blue, semi-translucent ice. Jupiter’s colorful orange, blue and cream-colored bands and swirling storms are visible in its atmosphere. In the middle distance, the Europa Clipper spacecraft can be seen, its solar panel wings glinting in the sunlight.

Hurry! You Can Catch a Ride to Jupiter with NASA

Well, at least your name can.  

One of the planet Jupiter’s largest and most intriguing moons is called Europa. Evidence hints that beneath its icy shell, Europa hides an ocean of liquid water – more water than all of Earth’s oceans combined. In 2024, our Europa Clipper robotic spacecraft sets sail to take a closer look…and when it launches, your name can physically be aboard! Here’s how: 

NASA’s Message in a Bottle campaign invites people around the world to sign their names to a poem written by the U.S. Poet Laureate, Ada Limón. The poem connects the two water worlds — Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored.

An illustration showing the planet Jupiter, its moon Europa with its cracked, icy surface, and the Europa Clipper spacecraft, all lined up against the dark background of space.

The poem will be engraved on Europa Clipper, along with participants' names that will be physically etched onto microchips mounted on the spacecraft. Together, the poem and names will travel 1.8 billion miles to the Jupiter system.

A poster with a background illustration showing the planet Jupiter and the surface of its moon Europa. The text reads: Message In a Bottle – Send your name. Next to the text is an illustration of a paper scroll rolled up inside a glass bottle sealed with a cork.

Signing up is easy! Just go to this site to sign your name to the poem and get on board. You can send your name en español, too. Envía tu nombre aquí.

The Europa Clipper launch window opens in October 2024, but don’t wait – everyone’s names need to be received this year so they can be loaded onto the spacecraft in time. Sign up by Dec. 31, 2023.

We hope you’ll be riding along with us! Follow the mission at europa.nasa.gov.

CONTENT‼️🗣

I’m officially declaring every Saturday on this blog to be Sea Temple Saturday. It will be the day of the week I set aside to post art, memes, or sh!tposts about anything relating to the Sea Temple or Vos. (I will of course be posting MCSM art and memes other days of the week, but you can always count on me posting at least one on Saturday.) Get ready for a gratuitous amount of joking that the temple is a brita filter, or that Vos canonically makes calls and texts from a walkie-talkie, or some other unhinged 3am thought I have. P.S. if y’all want to use this tag too, be my guest I think it’s amazing-

Anyways, happy Sea Temple Saturday everyone! I have a little something in the making already-

I’m Officially Declaring Every Saturday On This Blog To Be Sea Temple Saturday. It Will Be The Day

Shout out to the Sea Temple. Gotta be one of my favorite in-game locations-

I love that three houses took 3 of their shortest girls - Edelgard, Hilda, and Annette - and made two of them axe wielders by default and gave the other a massive axe relic called Crusher
