Time to renew my #CallforSpeakers - if you have some interesting results to share with the #HelsinkiUniversity #Astronomy & #Astrophysics community, please reach out! We will start the seminar again in September, with a mix of remote and in-person (hybrid) talks.

Ever wondered what a molecular cloud *looks* like??
#JWST & #Orion have you covered -- here we have OMC-2, which is a portion of a molecular cloud north of M42.

Roche Division Shadow Caster
The moon Prometheus casts a shadow on Saturn F ring near a streamer-channel it has created on the ring. The image was taken as the planet approached its August 2009 equinox.

Saturn and 4 Icy Moons in Natural Color
This approximate natural-color image shows Saturn, its rings, and four of its icy satellites. Three satellites (Tethys, Dione, and Rhea) are visible against the darkness of space, and another smaller satellite (Mimas) is visible against Saturn's cloud tops very near the left horizon and just below the rings. The dark shadows o...

Farewell to Mimas
In its season of "lasts," NASA's Cassini spacecraft made its final close approach to Saturn's moon Mimas on January 30, 2017. At closest approach, Cassini passed 25,620 miles (41,230 kilometers) from Mimas. All future observations of Mimas will be from more than twice this distance. This mosaic is one of ...

Streaked Craters in False-Color
A false-color view of Saturn moon Mimas from NASA Cassini spacecraft accentuates terrain-dependent color differences and shows dark streaks running down the sides of some of the craters on the region of the moon that leads in its orbit around Saturn.

Taking a Bite Out of Tethys
Dione steps in front of Tethys for a few minutes in an occultation, or mutual event. These events occur frequently for the Cassini spacecraft when it is orbiting close to the ringplane

Mimas Mountain
Shadows cast across Mimas' defining feature, Herschel Crater, provide an indication of the size of the crater's towering walls and central peak. Named after the icy moon's discoverer, astronomer William Herschel, the crater stretches 86 miles (139 kilometers) wide -- almost one-third of the diameter of Mimas...

Dot Against the Dark
As if trying to get our attention, Mimas is positioned against the shadow of Saturn's rings, bright on dark. As we near summer in Saturn's northern hemisphere, the rings cast ever larger shadows on the planet. With a reflectivity of about 96 percent, Mimas (246 miles, or 396 kilometers across) appears ...

Stretched Shadow
The shadow of Saturn moon Dione, cast onto the planet, is elongated in dramatic fashion in this image captured by NASA Cassini spacecraft. The moon itself does not appear here, but the shadow can be seen south of the ringplane.
