Leon Gurevitch - Turning astro data into images

Edwin Rod
 

Leon Gurevitch from Victoria University’s School of Design

 

This was a very interesting talk about photography then moving into the world of digital photography, using the EXIF information to look at the bigger trends.

He been at this university for a long time and its hard to believe out paths have never crossed until the talk last night.

 

Turning astro data into images

From the earliest attempts to capture the Moon with wet plate photography to the work of mid-twentieth century amateur astronomer-photographers, astrophotography has been seen as a dance between professionals and amateurs. In his talk for our May meeting, A/Professor Leon Gurevitch from Victoria University’s School of Design will ask what the history of astrophotography tells us about contemporary practices of astral image capture. By way of example, he will show us his own digital astrophotographic images taken all over the world, and introduce a large-scale image data visualisation project.

Hi everyone

 

Plenty of interesting items out this month, Highlights are the Ingenuity helicopter on mars, it’s been amazing to watch the videos. There was also a flare on Proxima centaur too that I need to read up on. Mike Brown has an interesting update on the search for an outer ice giant planet, new modelling suggests 5 earth masses and a different orbit?

There is an update on the RASNZ conference along with an update from John D as well to read.

Tonight’s Moon rise from home is also added in too.

It been a full on month and it’s amazing I have added this items together.

Cheers Edwin

This months news and research items

Edwin Rod
 

Hi everyone

 

Please find this month’s newsletters and star charts attached. This month there is an interesting number of papers and news items on my favorite class of stars, looking at planets around red dwarfs so plenty to read there. Speaking of Planets news broke of a possible planet around Alpha centauri A which is something we all need to keep a watch on. There is also a look at how many interstellar objects are captured by our solar system. New research on a possible outer planet arrived out this month and it’ too hard to say either way really, as usual Mike Brown had something to say on the subject. Starlink was back in the news and I read a good article from the ESA on re entry times for satellites which was very interesting. I managed to catch the live landing of Perseverance to which was a highlight this month so lots of images there along with news too.

 

So plenty of papers and news items to keep you all busy reading this month and your probably under some form of Covid lockdown so you will have the time for some reading, Currently were at Level 2 in Wellington (3 In Auckland).  


Cheers Edwin

Not Yet Imagined: A Study of Hubble Space Telescope Operations

Edwin Rod
 

Not Yet Imagined: A Study of Hubble Space Telescope Operations



Hi everyone this looks like a great e-book to download and have a read of.






By Christopher Gainor

The Hubble Space Telescope (HST) is the most famous astronomical instrument of its time and one of the best-known robotic vehicles ever put into space. Its launch and deployment into low-Earth orbit from the Space Shuttle Discovery in April 1990 appeared to fulfill the plans and dreams of astronomers since the beginnings of space exploration to place a telescope beyond the distorting effects of Earth’s atmosphere.

The first images from Hubble contained a stunning surprise—the space telescope’s main mirror had been precisely ground to the wrong shape. Although HST’s images were still superior to anything available from ground-based telescopes, the Hubble Telescope instantly became a byword for incompetence.

With the future of NASA on the line, scientists and engineers devised fixes for the spherical aberration afflicting Hubble, and astronauts flying on the first of five servicing missions to HST installed new instruments that restored the Space Telescope’s capabilities to those promised when it was launched. Within weeks, HST produced the breathtaking images and other data that astronomers and the public had long anticipated, and soon Hubble shed its former image as it became a symbol of American technological and scientific prowess.

Not Yet Imagined documents the history of HST from its launch through its first 30 years of operation in space. It focuses on the interactions among the general public, astronomers, engineers, government officials, and members of Congress during that time. The decision-making behind the changes in Hubble’s instrument packages on servicing missions that made HST a model of supranational cooperation amongst scientists is chronicled, along with HST’s contributions to our knowledge about our solar system, our galaxy, and our universe. This book also covers the impact of HST and the images it produces on the public’s appreciation for the universe, and how HST has changed the ways astronomy is done.

Merry Christmas everyone.

 

Please find the attached usual newsletters, I haven’t had this month’s star charts for this month, but if you’re in New Zealand you might not have had much use for them anyway! According to the Met service it’s the worst November ever recorded for Wellington and I’m sure not much better across NZ. Its raining again at the moment and around 12c outside just after the summer solstice here!

There is a range of interesting research out this month, the possible discovery of a signal around Proxima really caught my attention, and there are a range of links to news items on that one to follow up on. Andrew has again taken a good look at the Chinese lunar sample return this month.

Well lets hope 2021 is a brighter year for everyone.

To finish off the year I have attached my best image of Jupiter and Saturn

 

Cheers Edwin

Hi,

Currently there's a mag 7-ish comet in the morning sky (Comet Erasmus). It rises just before astro twilight. It could be a reasonable astrophotography target (albeit, we're fighting trilight down here in NZ). Here's an observation from J. J. Gonzalez Suarez (Spain) -

C/2020 S3 (Erasmus):

Tail= 0.4 deg. in PA 270 deg, 25x100B.

Hi all

John sure has been busy since I last made it out to his observatory complex near Martinbourgh the trees have grown and the observatories too. It’s a real credit to John and his team, with the total covid lockdown in 2020 and a mess of a year it was nice to make it out for the observatory opening and catch up with everyone. Here is a selection of the scopes, equipment and observatories.

They are already very close; as you say, great views to come. My eyesight is not what it was and stars/planets present as elongated spikes (distance glasses clean it up nicely) - I doubt I'll be able to separate them at their closest (without my glasses). Telescopic views will be magic Emoji.

Hi everyone

Please find all the usual star chart’s and newsletters attached along with a few interesting bits of research.

There is a good look at the search for the proposed outer ice giant this month and some great ones looking at habitable planets too.  The Leo labs tool looking at orbiting objects is lots of fun to have a look at.

 

Cheers Edwin

Water on Sunlit Surface of Moon

Edwin Rod
 

Hi Everyone

Important news requires an important update. Attached are two interesting papers about the Moon and water on the surface to have a look at. The observations were made from SOFIA which often operates from Christchurch.

The NASA news item is also linked below, now when we will make it back?

Super interesting so I will let you all read on.

Cheers Edwin

October 2020 News research and Star Charts

Edwin Rod
 

Hi everyone

Please find this month’s news, starcharts and as always a few of this month’s best research items.

 

You will be pleased to know the satellite Collison didn’t happen it sure was a nice day so I went out and took a few photos, and I have attached one taken around 2pm at the predicted time of re entery over wellington. There are two really interesting articles to read on the subject. The story behind Donald J. Kessler was very interesting and something I had never read about before.

Again Andrew has a range of interesting updates for us too including looking at Bennu and the sample collection a mission I know he’s been following closely.

If your looking for a full update on the Venus news I have managed over the last month to collect up all the bits of research on the phosphine discovery but top of the list are suggestions that the measurement was an error. Either way a new mission back to Venus is needed to study the clouds and map the surface in detail.

Remember it’s the Astrophotography camp in November and I’m hoping to make it along for one night.

Thanks Edwin
