November Supermoon 2016: Best Photos From Across the Globe

Marseille, France- Last night's supermoon was the biggest we'll see until 2034. Appearing 14% larger and 30% brighter than usual, the stunning spectacle was a sight to behold in many countries across the globe. According to NASA, the full moon of November 14 was not only the closest of 2016, but the closest moon to date in the 21st century. The New York Times reports that on an average day, the moon is about 238,900 miles away from Earth, and on Sunday and Monday, it was about 221,524 miles away. Read more...

Nova confirmed ! TCP J18102829-2729590

 Visit page
 A confirmation spectrum of TCP J18102829-2729590, a galactic nova in Sagittarius. The target, setting rapidly in the west, was imaged using the Alpy 600 under challenging conditions, providing confirmation as a classical nova in the optically thick stage. The resulting ATel (kindly prepared by Steve Shore, University of Pisa) can be found here. Additional spectra at both high and low resolution have been acquired and made available via the ARAS spectral database.

Naval Hill Planetarium 22 & 29 October





Tickets for the weekend of 22 and 29 October 2016 shows are available at Computicket.

22 October, 17:30
City of Stars (English)
We see the Milky Way as a faint glowing band arching across the sky. Though beautiful, our view with the naked eye is very limited. Come and discover more about our “city of stars”, its spectacular spiral structure, and its immense size. Explore the role of dark matter and explore the colourful star clusters and nebulae in the disc of the Milky Way. Fly into the centre, to our own supermassive black hole, then fly out far beyond the Milky Way to behold the recently discovered Laniakea Supercluster. Travel far into the future to see the inevitable collision of our Milky Way with our nearest spiral neighbour, Andromeda.

22 Oktober, 17:30
City of Stars (English

Die Melkweg kan snags gesien word as ‘n dowwe gloeiende band wat ‘n boog oor die hemelruim span. Hoewel dit pragtig is, is ons uitsig daarvan met die blote oog baie beperk. Kom ontdek meer van ons “stad van sterre”, die skouspelagtige spiraalstruktuur en die enorme grootte daarvan. Ontdek die rol van donker materie en verken die kleurvolle stertrosse en gasnewels in die skyf van die Melkweg. Vlieg tot in die kern, waar ons eie super-massiewe gravitasiekolk is, en tot ver buite die Melkweg om die onlangs ontdekte Laniakea supertros rondom die Melkweg te aanskou. Reis tot in die verre toekoms om die onvermydelike botsing van ons Melkweg met ons naaste spiraal-buurman, Andromeda, te aanskou.

Die Kaartjies vir die naweek van 22 en 29 Oktober vertonings is beskikbaar by Computicket.

Vanaf die aarde na die heelal (Afr)
This voyage through space and time conveys the Universe as revealed to us by science through the ages. Revel in the splendour of the worlds in the Solar System. Travel to the colourful birthplaces and burial grounds of stars. Fly beyond the Milky Way to the unimaginable immensity of myriads of galaxies.

Fly me to the moon (Eng)
The moon is our nearest neighbour and the only other celestial body we've set foot on.​ Its orbit around the Earth has a big influence on the planet and it dominates our night sky. The six manned missions to the moon have left more than just footprints, and are still contributing to science today.
  • Weather permitting - ASSA Bloemfontein will have a telescope at the planetarium to observe  the moon.

Naval Hill Planetarium - New Horizons: Painting a portrait of Pluto



New Horizons: Painting a portrait of Pluto
Public talk by leading NASA engineer

Place / Plek: Naval Hill Planetarium
Date / Datum: Monday / Maandag 3/10/2016
Time / Tyd: 18:15 for 18:30

Free - No booking required / Gratis - Geen bespreking is nodig nie

Launched in 2006, the New Horizons spacecraft was sent on a decade-long trek to gather data from Pluto, one of the most endeared and debated bodies in our Solar System. After swinging past Jupiter for a gravity boost, the tiny spacecraft gained enough speed to make its closest approach of Pluto on 14 July 2015, and conducted a six-month-long reconnaissance flyby study of the (now) exoplanet and its moons. Because of the distance from Pluto to Earth (five billion kilometres), the massive amount of data collected from the fly-by continues to stream back, offering new insights into Pluto and the space environment at the Solar System’s outermost regions. So what have scientists learned about the enigmatic Pluto? And what does the future hold for the tiny spacecraft? Join NASA Deputy Chief Technologist (Retired), Jim Adams, to find out.

Jim Adams
NASA Deputy Chief Technologist, Retired
  
Jim Adams retired as NASA’s Deputy Chief Technologist in September 2016 to focus on the development of young and emerging innovators and entrepreneurs by encouraging creative processes and innovative thinking. He served in NASA’s Office of the Chief Technologist at NASA Headquarters, Washington, DC from 2012, where he was responsible for the management of the technology strategy and innovation initiative across the entire agency.

Jim’s more than 25-year career at NASA saw him work on over 30 successful space missions. He was also the recipient of three NASA medals recognising exceptional service, including NASA’s Outstanding Leadership Medal.
 
Mr Adams’ travel is provided by SKA Africa in support of 2016 World Space Week, 4-10 October 2016.

Jim holds a BSc in Physics from Westminster College and a MSc in Electrical Engineering from Villanova University.

Apparently, he bakes a mean apple pie, but this is yet to be confirmed by a reputable judge in South Africa.
