📡 We reveal planet-forming structures in small disks. 📷: 11 compact disks of planet formation in the Lupus region. The comparison illustrates planet formation at distances comparable to those of our own solar system. almaobservatory.org/en/press…
ALMA images of the 11 compact planet-forming disks observed in the Lupus star-forming region. Using the highest angular resolution available with ALMA at a wavelength of about 0.9 millimeters, astronomers revealed previously hidden structures in several of these small disks. The lower-right panel shows the orbits of Earth, Mars, Jupiter, and Saturn, together with the asteroid belt, for scale. The comparison illustrates how these observations probe planet formation at distances comparable to those within our own Solar System. Each white scale bar represents two astronomical units; one astronomical unit is the average distance between Earth and the Sun. Credit: P. Curone et al. – ALMA (ESO/NAOJ/NRAO)

Using @almaobs 's sharpest observations, astronomers have uncovered rings and gaps in compact disks, raising new questions about how planets form close to young stars. techexplorist.com/tiny-plane…

Tiny planet-forming disks reveal a big surprise about how planets are born

Hidden gaps in tiny disks could point to planets still forming.

Radio #ImageoftheWeek Meet NGC 253, aka the Sculptor Galaxy! 🌌 At ~11.5 million light-years from Earth, it is one of the closest starburst galaxies to the Milky Way. Starburst galaxies transmute gas into new stars up to 1,000 times faster than typical spiral galaxies! More ⤵️
