Spaceburger 🍔 Gomez's Hamburger shows a Sun-like star near the end of its life, casting off layers of gas and dust. The "buns" are light reflecting off dust, and the "patty" is the dark band of dust in the middle. Learn more for Hamburger Day: go.nasa.gov/3PTqDJQ
Two glowing white lobes of cosmic material shine on either side of a dark black disk of dust, loosely resembling a hamburger. The black background of space is dotted with several stars.

Atlas hits a perfect rabona. Even on the simple kick, the follow-through mechanics look so human. Hyundai is an official sponsor of the FIFA World Cup. They're using Boston Dynamics Atlas as the branding hero. Hyundai has a controlling stake in Boston Dynamics.

XF7 Space Crew, Six years of driving on Mars is more than a cool timelapse. NASA says these images span 2020 to 2026, and every stretch of rover travel helps scientists connect rock layers, track surface change, and understand how Mars changed over time.

A rover wheel track is almost like a notebook line on Mars. Over time, movement across different terrain helps connect younger and older layers, which is one reason long missions like Curiosity are so powerful for reading the planet’s history.

ALT This animation shows the entire southern ecliptic sky in shades of blue-gray, imaged by the Transiting Exoplanet Survey Satellite (TESS). The image builds up individual sectors of the sky, which are each roughly rectangular with a grid of dark lines that look like a windowpane, in a counterclockwise direction. The bright band of the Milky Way, the central plane of our galaxy, arcs through the scene at left. The Milky Way appears as white speckles and blurry clouds on a darker background. The south ecliptic pole lies at the center, within the dark spot to the right of the Milky Way. Below it shines the Large and Small Magellanic Clouds, nearby satellites of our galaxy, as smaller white spots. This image is watermarked with \u201CCredit: NASA/MIT/TESS and Ethan Kruse (University of Maryland College Park).\u201D

Endurance is going through a variety of tests ahead of launch in Florida. First one complete: modal testing ✅ We used sensors to measure how our lunar lander will respond to launch conditions. The test was performed with Endurance mounted on both the New Glenn flight Launch Vehicle Separation System (LVSS) and a GS2 payload adapter.

XF7 Space crew, A fresh Hubble view shows the Crab Nebula glowing with tangled, colorful filaments. NASA says this observation from Hubble, released on March 23, 2026, helps astronomers study how this supernova remnant is expanding and evolving over time. NASA says the nebula’s filaments moved outward over 25 years at about 3.4 million miles per hour.

XF7 Space Crew, Hubble birthday week starts with a great reminder that nebulae are not just pretty clouds. NASA says this Trifid Nebula view shows a star forming region where intense ultraviolet light from massive young stars is shaping the surrounding gas and dust.

Welcome to Hubble's 36th birthday week! ✨🎂 We're kicking things off with a new view of the cosmos, courtesy of the telescope-of-honor. Hubble captured brilliant details of the Trifid Nebula, a star-forming region about 5,000 light-years from Earth: go.nasa.gov/4sJ7dEU
A tightly cropped Hubble view of a vast star-forming region known as the Trifid Nebula. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns. The left horn points left and is wavy. The right horn is triangular and points up. The brown dust continues, flowing down, as if along a back, and up toward the top right. A prominent line, about the same length as the left horn, appears below the middle of the body, and changes from orange to red. A small, separate semi-transparent pillar is left of the head. A few slightly larger, blue foreground stars with four diffraction spikes appear throughout.

One fun science point here is that stars can shape the clouds they are born in. Hubble’s new close up shows how radiation from young massive stars can sculpt nearby gas and dust while new stars are still forming in the same region.

XF7 Space Crew, This is why Curiosity still matters. NASA says the rover found the largest organic molecules yet detected on Mars in a rock sample from Gale Crater. That does not mean life was found, and it does mean Mars preserved more complex carbon chemistry than we had seen before.

Mars keeps getting more chemically interesting. The big science lesson here is that a life clue is not the same as a life claim, and careful missions like Curiosity help us separate those two step by step.
