Parker Solar Probe Captures Superb Image Of Venus

NASA’s Solar Probe Captures Amazing Image During Venus Flyby

February 27, 2021

While all eyes have been on Mars this week, NASA’s Parker Solar Probe, which is studying the structure and surface of the Sun, as well as gathering data on solar winds, used a close approach to the planet Venus to beam back some stunning photos, which were actually imaged last year.

We know Venus as a planet with a runaway greenhouse effect that lifts surface temperatures to an average of 864 degrees Fahrenheit, and is obscured by an atmosphere of poison gases, but the spacecraft managed to actually image the highest landform on the planet. The atmosphere is so thin at that height that the geologic feature was picked up by the visible light camera. The area, known as Aphrodite Terra, experiences an average high temperature of only 85 degrees due to its altitude.

The probe’s Wide-field Image camera also captured an eerie shine around the edge of the planet, which NASA says may be due to ‘nightglow,’ or “light emitted by oxygen atoms high in the atmosphere that recombine into molecules in the nightside.”

Excited about the images, project scientist Karl Battams also tweeted about a spot on the camera lens that made it appear as if there was an anomalous feature in the Venusian clouds, saying “I see a few comments online about this blob in our Venus image – it’s a defect on the camera lens (can be seen in all our data). #ItsNeverAliens”

During its mission, the Parker Solar Probe is scheduled to closely approach Venus a total of seven times in order to change its orbit around the sun, taking it closer with each “gravity assist” maneuver.

Oh man, the hits just keep rolling in!

 

Did We Just Detect Life on Venus?

Cool Worlds
Sep 14, 2020

The announcement of the detection of a possible biomarker in the atmosphere of Venus has shook up the field of astrobiology and grabbed headlines across the world. Today, we explore why Venus could plausibly host life, how this detection was made, and whether it really means that we’ve finally found extraterrestrial life. Written and presented by Prof Kipping, featuring guest Dr Caleb Scharf.

RAS Press Briefing – Phosphine on Venus

Royal Astronomical Society
Streamed live on Sep 14, 2020

The Royal Astronomical Society press briefing held on 14 Sep 2020, discussing the detection of phosphine in the cloud decks of Venus. See ras.ac.uk/news-and-press/news… for full details of the discovery.

Hey, I know, I know, it’s rather late. From September, even. I spaced it. But that doesn’t make it any less thrilling! I mean… Extraterrestrial Life!

Things are bonkers around here. Really stressful times, since the middle of August. Sigh.

Wow, this view is simply spectacular!

And, I dare say, a decidedly beautiful view it is.

I’m excited!

 

BepiColombo Venus Flyby

About Space Only
Oct 22, 2020

A sequence of images taken by one of the monitoring cameras on board the European-Japanese BepiColombo mission to Mercury, as the spacecraft made a close approach of Venus on October 15, 2020.

This sequence of 64 images was captured by Monitoring Camera 2 onboard the Mercury Transfer Module from 40 minutes before until 15 minutes after closest approach of 10,720 km from Venus. The images were taken every 52 seconds. The camera provides black-and-white snapshots in 1024 x 1024 pixel resolution.

In these images, Venus appears in the top right behind the Mercury Planetary Orbiter’s magnetometer boom and moves across the field of view towards the spacecraft’s medium gain antenna. The shape of the terminator — the boundary between the fully illuminated planet (day) and the fully shadowed area (night) — clearly changes, showing that the spacecraft’s path curves around from the dayside to the nightside.

The images have been lightly processed to enhance the brightness and contrast. The illuminated disk of Venus is so bright that it is saturated in these images, even using the shortest possible camera exposure time. At the planet’s terminator, some very faint structures are visible, but these appear to be due to ghosting in the camera optics rather than features in the atmosphere of Venus. There is also some horizontal striping in the images due to effects in the electronics.

The gravity assist maneuver was the first at Venus and the second of nine flybys overall, which help steer the spacecraft on course for Mercury. During its seven-year cruise to the smallest and innermost planet of the Solar System, BepiColombo makes one flyby at Earth, two at Venus and six at Mercury to brake against the gravitational pull of the Sun in order to enter orbit around Mercury.

BepiColombo, which comprises ESA’s Mercury Planetary Orbiter and the Mercury Magnetospheric Orbiter of the Japan Aerospace Exploration Agency (JAXA), is scheduled to reach its target orbit around the smallest and innermost planet of the Solar System in 2025.

A look at a far away place.

Space exploration is a wonderful, beautiful thing.

 

This is so totally awesome!

“The best evidence for life beyond Earth has been found in the most surprising of places – the atmosphere of Venus.

A team led by Jane Greaves, who is a professor at Cardiff University, has detected the presence of phosphine gas in Venus’ clouds. The intriguing thing about phosphine, which is a molecule formed of three hydrogen atoms and one phosphorous atom, is that on Earth its only natural source is from some anaerobic (i.e., non-oxygen breathing) microbial lifeforms. No known geological mechanism or non-biological chemical reaction produces it on our planet, although it is produced deep inside gas giants like Jupiter and Saturn where hydrogen is plentiful and the temperature and pressure extremely high.”
