two questions!

1-what was the scrapped lore reason for the sky city portal being in Jesse's world (as you mentioned exploring that if it never got explained?)

2-I forget if you've mentioned it before but what's the Sidekick Academy?

1 - We had considered the idea that maybe it was the portal that Soren first used to enter Jesse’s world but it opened up too many other questions and ultimately just wasn’t very interesting to make a concrete answer.

2 - So I’ve talked about this in bits and pieces, but Jack’s backstory is that he was a scrappy wannabe hero in a town that was like a superhero story and a fantasy world blended into one - Taverns and quests and things but with more outlandish characters with gimmicks and things. This town had a big academy for heroes that was very tough to get into, and also a school for the sidekicks that weren’t good enough to be heroes or just didn’t want to be in the spotlight. That sidekick academy is where Jack and Vos met - Vos was a potions and enchantments expert who wanted to be on the sidekick track, and Jack was stuck as a “stick boy”, gathering the sticks to make swords and other equipment for the heroes. He really, really, wanted to be on the hero track, but he was just too impulsive and also didn’t have a “gimmick” like a lot of other heroes. He just.. wanted to help people. He finally gets his shot when a big bad villain comes to town who drains the power from heroes so only the sidekicks are left to save the day. This was also the adventure where they met Nurm (the latest in a long line of talenting mapmakers who is in a broody emo phase of rejecting his family business, and who they need to talk into helping them make a map to follow the big bad) and Sammy (a master thief and con artist who could be a hero and star of the hero academy if she didn’t think they were all such dorks)

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.
