When a young star forms, a ring of gas and dust called a protoplanetary disk forms around it. Together, the star and the disk are a young solar system, and peering into solar systems much younger than ours reveals clues about how planets form in protoplanetary disks. Our most powerful tool for examining these young systems is ALMA, the Atacama Large Millimeter/submillimeter Array.

In June 2020, the ESA's Solar Orbiter (SolO) mission launched and became the closest mission ever to orbit the Sun and take images of its surface. In March 2025, the mission made history by becoming the first probe to acquire images of the Sun's polar regions. Until now, all missions have taken images of the Sun's equatorial region because it corresponded to their orbits around the ecliptic plane. But thanks to the Solar Orbiter spacecraft's tilted orbit, it was able to observe the Sun from a whole new perspective.

The Vera C. Rubin Observatory, constructed in Chile's Atacama Desert, houses perhaps the most powerful survey telescope ever built. Named after the pioneering astronomer who provided crucial evidence for dark matter, the telescope features an 8.4-meter primary mirror and the world's largest digital camera at 3.2 gigapixels. It’s plan…. to conduct the Legacy Survey of Space and Time (LSST), photographing the entire visible southern sky every few nights for ten years. This unprecedented survey will catalog billions of galaxies and stars, track moving objects throughout the Solar System, and help scientists study dark matter, dark energy, and the changing universe with remarkable precision.

Mars, often called the Red Planet due to its distinctive rusty color from iron oxide on its surface, is Earth's neighboring planet and humanity's most likely next destination for exploration. It’s about half the size of Earth and takes nearly two years to complete one orbit around the Sun. Mars is home to the largest volcano in our solar system, Olympus Mons, as well as a massive canyon system called Valles Marineris. It continues to fascinate scientists who are searching for signs of past or present life while planning for the day humans pay a visit.

Advanced telescopes take a lot of advanced technologies to build, and many times those technologies come from companies rather than the space agencies that sponsor the project. The most recent example of this is the Laser Interferometer Space Antenna, or LISA, whose project sponsor recently signed a contract to begin construction of this mission that will eventually expand our search for gravitational waves.
