Warning: The following contains spoilers for Avengers #27 by Jason Aaron, Ed McGuinness, Mark Morales, Jason Keith and Cory Petit, on sale now.
After the Marvel Legacy relaunch, the Avengers established a new base of operations in the form of the massive, cosmic body of a dead Celestial. Thanks to its ancient but highly advanced nature, the Celestial offers plenty of room for Earth's Mightiest Heroes, as well as useful defense systems and technologies they never had access to before. While it's big enough for each of Marvel's heroes to have a room of their own, it's also a heavily fortified and weaponized fortress that can house and protect hundreds of refugees if Frost Giants or other giant-size foes come knocking.
Another piece of the technology that comes with living in a dead Celestial is revealed in Avengers #27, which sees the super-team head off into space for a new mission. As they do so, they use a new means of traveling through the cosmos that seems remarkably similar to a method that we've seen in the Marvel Cinematic Universe.
As this new team of Avengers prepares to head off into space, they board their new spaceship, which is docked inside one of the Celestial's fingers. After blasting off into the atmosphere, Captain Marvel activates the "Celestial Warp Tech," and the ship disappears into a Kirby-esque portal etched in the starry sky. As we understand it, the Celestial technology now enables the Avengers to open portals to travel from one corner of space to the other, instead of taking the long way around.
This technology is remarkably similar to what the Avengers and the Guardians of the Galaxy use in the MCU. In James Gunn's Guardians of the Galaxy films, we were introduced to the principal mode of long-range travel in the cosmos at large: jump-points.
These jump-points are essentially a network of portals that are scattered throughout space, and they allow spaceships to reach one sector of the galaxy to the next. Movies such as Captain Marvel and Avengers: Endgame continued to show the use of these jump-points, while Guardians of the Galaxy Vol. 2 gave a memorable warning of what happens when one ship uses them too much.
Avengers #27's Celestial Warp Tech isn't exactly the same thing as the MCU's jump points, but the two are similar. After all, both open up portals that allow spaceships to travel from one point of space to the other. It's been useful in the films, and it's bound to become even more useful in the comics.
While Marvel's comic book heroes have never seemed to have much trouble traveling into deep space, these portals essentially put the galaxy at their fingertips, much like the X-Men's Krakoan portals to the Moon and beyond. Even though they're just starting to use this technology, the Avengers can reach their destinations much faster, which is bound to open up even more stories in the farthest reaches of the Marve Universe.
