Face to face with Sun-eclipsing Proba-3


Recommended Posts

Proba-3's pair of satellites

Through exquisite, millimetre-scale, formation flying, the dual satellites making up ESA’s Proba-3 will accomplish what was previously a space mission impossible: cast a precisely held shadow from one platform to the other, in the process blocking out the fiery Sun to observe its ghostly surrounding atmosphere on a prolonged basis.

      The sun appears to be angry; a massive coronal mass ejection unveils a striking image resembling a grimacing demonic face. Striking are the letters DV (DeVil?) standing out on the forehead of the figure. 

      Obviously, the strange phenomenon captured by NASA's solar satellite SOLO EUI HRI 174 on 2024/05/11 is an ordinary natural occurrence triggered by the eruption of solar material but a fact is that a huge CME hit Earth's magnetic field on May 10th, leading up to the biggest geomagnetic storm in almost 20 year. 
      And it is not yet over as forecasts predict additional coronal mass ejections to follow closely behind, prolonging the storm well into the weekend. Anticipation mounts for widespread auroras, promising captivating displays over regions like Europa and the United States. 
      The storm has now reached level G5 which is the strongest level of geomagnetic storm, on a scale from G1 to G5. The solar storm could lead to disruption of satellite communication systems, low-frequency radio navigation systems such as GPS or even widespread power grid failures. 
      This unique solar phenomenon emphasizes once more the importance of constant monitoring and readiness in response to solar disruptions in order to prevent another Carrington event which was the most intense geomagnetic storm in recorded history, peaking from 1–2 September 1859.

      Glenn Hangar Has Long Been the Face of the Center
      Painters completing work on NASA Glenn Research Center’s new hangar roof design in July 2016. It was the first time that the roof featured an insignia.Credit: NASA/Bridget Caswell The Flight Research Building, or hangar, at NASA’s Glenn Research Center in Cleveland has not only housed the center’s aircraft and Flight Operations team for decades, but has also served as a visual representation of the center for the public. NASA has taken advantage of the hangar’s size and shape — along with its location near the center’s main entrance, the Cleveland Hopkins International Airport, and multiple freeways — to raise awareness about Glenn to both the local community and Cleveland visitors.
      In the fall of 1941, the National Advisory Committee for Aeronautics (NACA) completed the first building at its Cleveland laboratory: the hangar. The letters “N-A-C-A” over a pair of wings were installed above its front and back aircraft entrances shortly thereafter. In 1946, “N-A-C-A” was painted in large white block letters onto the black roof facing the airport. This configuration remained in place for twelve years.
      Pilot Bill Swann climbs into the cockpit of a McDonnell F2H-2B Banshee at the Lewis laboratory in February 1958. Eight months later, the NACA logo on the hangar was removed as the NACA became part of NASA. Swann, who joined the NACA in 1945, spent 35 years flying Lewis aircraft before retiring in 1980.Credit: NASA/Ernie Walker On Oct. 1, 1958, the NACA disbanded, and the laboratory was incorporated into NASA — the nation’s new space agency — as the Lewis Research Center. The next day, the “C” on the hangar roof was painted over with an “S,” and two weeks later, the NACA wings on the front and back were taken down and replaced with small “N-A-S-A” lettering.

Credit: NASA During this period, the new agency asked its employees to submit concepts for an official seal. In December 1958, the NASA administrator approved the design of James Modarelli, a graphic illustrator at Lewis and head of the Technical Publications Division. Soon thereafter, he was asked to create a simpler, easier to reproduce version to be used more broadly. In early 1959, Modarelli came up with the large blue insignia that later became known as the “meatball.”
      In September 1962, a large NASA insignia was installed on the front entrance of the Lewis hangar facing Brookpark Road, where it remained along with the “N-A-S-A” letters on the back and roof for nearly 30 years. In an effort to rebrand the agency in the mid-1970s, NASA replaced Modarelli’s blue insignia with the highly-stylized logo type, also known as “the worm.” Although the change of logos was mandated, the meatball never fully went away, and it remained on the front of the Lewis hangar.

      With its fiftieth anniversary approaching in 1991, the center began developing strategies to improve its visibility in the community. The most significant action was a redesign of the hangar graphics. In November 1990, the large red worm logo was installed on the front, and “Lewis Research Center” was added below with lighting to make graphics visible at night.

Two large new meatball signs were constructed in the center’s shops to replace the worm on the front of the hangar and take the place of the 35-year-old insignia on the back. To mark the occasion, the center invited the retired Modarelli to participate in a rededication event at Lewis on Oct. 1, 1997. Modarelli and many of the 250 attendees signed their names on the back of the emblem, which remained above the back entrance until 2022.
      In 1993, Congress decided to rename the Cleveland facility the Glenn Research Center. By early 1999, the Lewis Research Center text on the front of the hangar was changed to “Glenn Research Center” with “Lewis Field” in smaller type underneath.
      The hangar roof was painted white in the early 1990s, first with black “N-A-S-A” letters, then with pale blue ones. In 2016, the center chose to repaint the roof with a large NASA meatball insignia, with “Glenn Research Center” in text below.
      The meatball remains today, a larger-than-life symbol of NASA Glenn’s presence in the community.

      On Sept. 7, 2023, during its 54th close flyby of Jupiter, NASA’s Juno mission captured this view of an area in the giant planet’s far northern regions called Jet N7. The image shows turbulent clouds and storms along Jupiter’s terminator, the dividing line between the day and night sides of the planet. The low angle of sunlight highlights the complex topography of features in this region, which scientists have studied to better understand the processes playing out in Jupiter’s atmosphere.
      As often occurs in views from Juno, Jupiter’s clouds in this picture lend themselves to pareidolia, the effect that causes observers to perceive faces or other patterns in largely random patterns.
      Citizen scientist Vladimir Tarasov made this image using raw data from the JunoCam instrument. At the time the raw image was taken, the Juno spacecraft was about 4,800 miles (about 7,700 kilometers) above Jupiter’s cloud tops, at a latitude of about 69 degrees north.
      JunoCam’s raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing. More information about NASA citizen science can be found at https://science.nasa.gov/citizenscience.

      Hubble Captures a Galaxy Face-On
      NASA’s Hubble Space Telescope captures the face-on spiral galaxy, IC 5332. ESA/Hubble & NASA, R. Chandar, J This glittering image from the NASA/ESA Hubble Space Telescope shows the spiral galaxy IC 5332. The galaxy lies about 30 million light-years away in the constellation Sculptor and has an almost face-on orientation to Earth. To understand the term ‘face-on,’ it is helpful to visualize a spiral galaxy as an extremely large disk. If the galaxy’s orientation makes it appear circular and disk-shaped from our perspective on Earth, then we say that it is ‘face-on.’ In contrast, if the galaxy’s orientation is such that it appears squashed and oval-shaped, then we say that it is ‘edge-on.’ The key thing is that the same galaxy would look extremely different from our perspective depending on whether it was face-on or edge-on as seen from Earth.
      IC 5332 is an SABc-type galaxy in the De Vaucouleurs system of galaxy classification. The ‘S’ identifies it as a spiral galaxy, which it clearly is, given its well-defined arms of bright stars and darker dust that curl outwards from the galaxy’s dense and bright core. The ‘AB’ designation is a little more complex. It means that the galaxy is weakly barred, which refers to the shape of the galaxy’s center. The majority of spiral galaxies do not spiral out from a single point, but rather from an elongated bar-type structure. SAB galaxies – which are also known as intermediate spiral galaxies – do not have a clear bar-shape at their core, but also do not spiral out from a single point, instead falling somewhere in between. The lowercase ‘c’ describes how tightly wound the spiral arms are: ‘a’ would indicate very tightly wound, and ‘d’ very loosely wound. Thus, IC 5332 is an intermediate spiral galaxy on many fronts: weakly barred, with quite loosely wound arms, and almost completely face-on!
