Using +Hubble Space Telescope observations from the past and including recent observations this year, astronomers have measured the diameter of Jupiter’s Great Red Spot at approximately 10,250 miles across, the smallest ever measured.

Astronomers have known that the giant storm feature on Jupiter has been shrinking since the 1930s, and now we have several decades of observations that show just how much and at what rate.

By comparison, the Great Red Spot was 14,500 miles across when NASA’s Voyager 1 and Voyager 2 spacecraft flew by Jupiter in 1979.

Starting in 2012, amateur observations revealed a noticeable increase in the spot’s shrinkage rate. The GRS’s “waistline” is getting smaller by 580 miles per year. The shape of the GRS has changed from an oval to a circle. The cause behind the shrinking has yet to be explained.

These new observations also show that very small eddies are feeding into the storm and my be responsible for the sudden change  by altering the dynamics and energy of the Great Red Spot.

Please join +Tony Darnell and +Carol Christian as they discuss these new observations with Dr. Amy Simon and others and bring your questions and comments.  We look forward to seeing you there!

The Plextor M6e SSD uses the new M.2 standard to break free from the limitations of SATA, but it does so in a fairly interesting way by arriving pre-attached to a PCIe 4x add in card so that you won’t have trouble finding something it’ll fit in.

The James Webb Space Telescope will have four “cameras” at its disposal to explore the universe. The Near-Infrared Camera, or NIRCAM, will focus its attention on distant galaxies and help us learn more about planets around other stars. But NIRCAM is unique. Its vision will also be used to help align the telescope, a critical step in making the observatory function properly. Join “Behind the Webb” Host Mary Estacion as she visits the Lockheed Martin facility in Palo Alto, California to find out more about the making of NIRCAM.

“Behind the Webb” is an ongoing series that follows the construction of the Webb Space Telescope, Hubble’s successor. Find more episodes at Hubblesite.org.

The MK IV from Little Dot is a relatively inexpensive tube amplifier for your headphones that looks great and sounds great, but does comes with the usual tube amp caveats!

This video is the stereo 3D version of “Evaporating Peaks: Pillars in the Monkey Head Nebula”. Note that the zoom is 2D, and only the second part of the sequence has stereo 3D.

The Monkey Head Nebula (also known as NGC 2174) is a star-forming region in which bright, newborn stars near the center of the nebula illuminate the surrounding gas with energetic radiation. This radiation, along with strong stellar winds, erodes away the lower density gas. Pockets of higher density gas resist this erosion, and form pillars and peaks along the inner edge of the roughly circular cloud.

This video showcases visible and infrared light views of a collection of pillars along one edge of the nebula. The sequence begins with a view of the night sky near the constellation of Gemini and Orion. The view zooms through observations from the Digitized Sky Survey 2 to reveal a Hubble Space Telescope visible light view of the top of this region of pillars.

A cross-fade transitions not only between Hubble’s visible and infrared light views, but also from a two-dimensional image to a three-dimensional sculpted model of the region. The camera then pulls back to reveal the landscape of evaporating peaks of gas and dust surrounded by stars. Note that the visualization is intended to be a reasonable interpretation (not scientifically accurate) and that distances within the model are significantly compressed.
