SPHEREx

With Ja- the James Webb Space Telescope, we could take pictures of those birds and leaves and further off trees.

And with our survey telescopes like SPHEREx, which we launched last year, we can take panoramic views of the forest itself.

Roman does both.

It has that wide-angle view of the forest and the sharpness to see the birds and leaves on those trees.

We're basically making enormous three-dimensional maps of how galaxies are distributed in the universe, of how we think matter is distributed in the universe.

We launched, uh, the Euclid Space Telescope, the Nancy Grace Roman Space Telescope, and then we also have SPHEREx, and all three of them will be making these three-dimensional maps of the universe that will enable us to study dark matter on the one hand and dark energy on the other.

They're gonna gather data that's gonna allow us to much better constrain the properties of dark matter and dark energy.

But in doing so, we take surveys of big areas of the sky.

He is currently working on the SphereX engineering team at JPL.

The SphereX mission is a space observatory launched about a year and a half ago.

SPHEREx stands for Spectre Photometer for the History of the Universe Epic of Reionization and ICES Explorer.

The SPHEREx Observatory will collect data on more than 450 million galaxies, along with more than 100 million stars in the Milky Way in order to explore the origins of the universe.

Until then, space lovers, look up and wonder and find as many amazing cosmic structures in the night's summer sky.

They create streaks, uh, in the image from a ground-based telescope, but they also create streaks in the images from some, uh, telescopes that are also in low Earth orbit.

So NASA's got a telescope, uh, you know, called SPHEREx, which is doing a survey of the whole sky in the, in the mid-infrared, and that sees streaks from, from these, uh, thousands of telescopes and that's another reason we wanna send, uh, a telescope like Roman out to the Lagrange point because then we're very far away from Earth.

We're also very far away from these thousands of, uh, low Earth orbit, uh, satellites.

So we can add that to the list of reasons we're sending Roman to the Lagrange point.
