Flyby success! ESA's Juice spacecraft passed Venus at 07:28 CEST on 31 August.

This photo shows our deep-space antenna in Spain in communication with Juice during the flyby.

Juice’s current location, Venus, and its destination, Jupiter, are both visible in the sky ❤️

Some sights from Rocky Point State Park
A view of Narragansett Bay, with a moored sailboat and kayaker in the foreground, Jamestown Bridge in the distance. Close up photo of a wave breaking over a rock at the shore of Narragansett Bay. A tree and its shadow on a grassy field, with a lot of sky visible through the branches. A tree that appears to be leaning with the wind, silhouetted against a clear sky with small cumulous clouds in the distance.

What can we learn from our neighbors? 🌌

Our closest spiral galaxy, Messier 31 (M31), sometimes referred to as the Andromeda galaxy, is about 2.5 million light years away. Due to their similar structures, astronomers study M31 to understand our own Milky Way! 🔭 🧪

Great 🧵 about the importance of astronomical data archives and the role amateurs can play. Kudos to @astrafoxen.bsky.social and all others involved! 🔭

Hiya! Over the past few months I've been silently working on several astronomy projects. Here's what I've been up to lately! 🔭☄️🧪
1. I discovered a Kuiper belt object! (2013 CG269)
2. I'm coauthor of a brand new paper by @renerpho.bsky.social et al. on the rotation of asteroid Bradyharan!

(1/11)
This is a picture of the Kuiper belt object 2013 CG269, as seen by the Subaru Telescope on 24 February 2017. It shows a zoomed-in patch of sky, peppered with fuzzy white dots and smudges against a gray, grainy background. The white dot at the lower right is circled and labeled "2013 CG269" in yellow. Coincidentally, there is an unknown faint moon of Jupiter right next to 2013 CG269. This unknown moon of Jupiter is the fainter white dot located left of center, circled and labeled "Jovian moon" in cyan. A screenshot of a scientific paper titled "LIGHTCURVE AND ROTATION PERIOD OF 46925 BRADYHARAN" in bold. Below the bolded title are the authors, whose names from top to bottom are: Daniel P. Bamberger Sam Deen K. Ly (me!) Elvis Oliveira Mendes Arndt Schnabel Guy Wells To the right of the title and authors list are two rectangular plots with squiggly curves across them. The top right plot shows the brightness of asteroid 46925 Bradyharan over time, while the lower right plot shows the root-mean-square error (RMS error) of different rotation periods.

Remarkable new image of the Sun's surface from the @NSF Inouye Solar Telescope 🌞 🔭 ! The lower panel has been processed to reveal fine detail: linear features are just 20 km (12.5 miles) across! Managed by @NatSolarObs and @AURADC for NSF. Full story: nso.edu/press-releas...
Upper panel shows a golden-hued view of the surface of our Sun: Texas-sized solar convection cells known as granules are the result of curtain-like sheets of magnetic fields that ripple and shift like fabric blowing in the wind. As light from the hot granule walls passes through these magnetic “curtains,” the interaction produces a pattern of alternating brightness and darkness that traces variations in the underlying magnetic field. Lower panel: the same image has been processed to highlight the striations that separate the granules. THe precision of the Inouye telescope reveals structures on the scale of just 20 km (12.4 miles) on the Sun's surface!

#MarsExpress updates software, extends lifetime until 2034

A space mission is as durable as its most critical subsystems. For ESA's Mars Express, this subsystem is the gyroscope. Mission controlers have devised a way to considerably extend its lifetime.

NSF–DOE Rubin Observatory is about to do something never done before: #CaptureTheCosmos with a 3200-megapixel image every 40 seconds, all night, every night, for 10 years. That's 60 petabytes in raw images alone! 🔭🧪

How do you handle that much data?💾
