There is a close conjunction of a thin crescent Moon and Venus visible tonight just after sunset. Mercury is also visible but will be harder to spot in the glow of the sunset. Binoculars will show Venus and the Moon in the same field of view, reveal details of the Moon’s surface, and make it easier to isolate Mercury from the sky glow. But remember to never point binoculars towards the sun!
Stay up later to see Jupiter, Saturn and Mars. That makes up the 5 planets in one night identified by a CBC article. If you have a pair of binoculars, aim them at Jupiter around 10:30 pm to see four of Jupiter’s moons: Callisto, Ganymede, Io, and Europa.
P.S. You can view a sixth planet by looking down at some point during the night.
NASA has put its planet hunting Kepler space telescope into hibernation because it is running low on fuel. Kepler has discovered over 2,500 exoplanets by monitoring more than 150,000 stars for slight dips in brightness that might be caused by an exoplanet passing in front of the star.
NASA made the move to ensure that Kepler has enough fuel left to beam its latest data haul to its handlers early next month. Kepler has been on its 18th observation campaign since May 2018. It has been pointing at a patch of sky towards the constellation of Cancer that it previously studied in 2015. This second look will provide data that helps astronomers confirm previous exoplanet candidates. Returning the data back to Earth is the highest priority for the remaining fuel. On August 2, the team will command the spacecraft to awaken from its hibernation state, maneuver the spacecraft to point its large antenna back toward earth, and transmit the data over the Deep Space Network.
The Kepler mission launched in March 2009, with the goal of helping astronomers determine just how common Earth-like planets are throughout the Milky Way galaxy. Kepler has been tremendously successful by any measure. A key finding from he spacecraft’s observations suggest that about 20 percent of sunlike stars host a roughly Earth-size planet in the habitable zone (where liquid water could exist on a world’s surface).
Kepler’s primary mission ran through May 2013, when the second of the spacecraft’s four orientation-maintaining reaction wheels failed. The K2 mission was developed in the months following the failure with the novel concept of using sunlight pressure to help stabilize the spacecraft. K2 became fully operational in May 2014 allowing Kepler to continue making scientific observations.
The transit method of detecting exoplanets looks for slight dips in the brightness of a star when a planet passes in front of a it as viewed from Earth. We can observe an occasional transit of Venus or Mercury when they pass in front of the Sun and appear as a small black dot creeping across the Sun’s surface as seen from Earth.
After several transits are detected, the planet’s orbital radius can be calculated from the period (how long it takes the planet to orbit once around the star) and the mass of the star. The size of the planet is found from the depth of the transit (how much the brightness of the star drops) and the size of the star. From the orbital size and the temperature of the star, the planet’s characteristic temperature can be calculated. From this the question of whether or not the planet is habitable (not necessarily inhabited) can be answered.
The SpaceX CRS-15 Mission to the International Space Station launched from the Kennedy Space Centre in Florida at 2:42 am PDT this morning. In attendance were three students from the Nanaimo District Secondary School to witness a space mission that they have been working on since September.
The mission involves sending planarian flatworms into orbit to test the effects of micro-gravity and the supplement L-carnitine on muscle loss. A group of worms still in Nanaimo, and not sent into space, serve as a control group. Astronauts in space experience muscle mass loss and the experiment may yield insights that will help astronauts on extended missions.
The CRS-15 mission marked SpaceX’s fastest re-flight of a booster. The same booster launched the planet-hunting Tess satellite in April. The booster was topped with a used Dragon cargo spacecraft with 2,700 kilograms of supplies and science gear for the International Space Station. The cargo includes the spherical AI bot named Cimon, genetically identical mice, super-caffeinated coffee and the Nanaimo worms.
The Astronomical Association of Afghanistan is trying to establish Afghanistan’s first astronomy curriculum for young children set in the context of Afghan culture, Islamic astronomical heritage and modern science. Educational resources will be delivered to schools, orphanages and refugee camps in the Kabul area, and establish training and educational programs based on those materials. Once established in Kabul, the programs will expand to the rest of Afghanistan
A great part of the project is already in place. with experienced staff volunteering the time. Funding is being sought for the remaining resources to make this project a reality.
TheLittle Book of Stars is an introductory astronomy text for young Afghan children authored by Christopher A Phillips, edited and illustrated by Dr. Sai Pathmanathan, and translated into Pashto by Mujtaba Ilmi. Little Book of Stars covers astronomical topics from A-Z accompanied by cartoon illustrations. With an initial print run of 1000, Little Book of Stars will be distributed free to Pashto-speaking children in Kabul.
Kits containing pencils, pens, paper and astronomy education materials will be distributed.
A basic astronomy curriculum – in Afghan cultural context and drawing upon the rich astronomical heritage of Islam – is being developed in collaboration with the Afghanistan Astronomical Association. Activities include basic observational astronomy, solar observing, and fun classroom activities such as kinesthetic astronomy.
Astronomical outreach will also be conducted with children in classrooms, orphanages, and refugee camps around Kabul and in other major cities as the security situation permits.
These programs will change the lives of Afghan children. Inspiration, education, and experiences early in life have the greatest impact on who we become. The educators involved in this project have set a goal to bring that inspiration and life-changing experience to the least advantaged of children. They complement existing formal education programs, setting children on a course for a life beyond the turmoil of conflict, and economic and social inequality.
RASC Vancouver is participating at Vancouver Illuminatedon Saturday, June 2nd, 2018.The City of Vancouver and the H.R. MacMillan Space Centre have teamed up to present an evening of discovery about Vancouver’s night sky and an opportunity to engage residents about the City’s Outdoor Lighting Strategy.

Congratulations to Carl Bandura who correctly identified the galaxy as NGC 4564 – an 11th magnitude elliptical galaxy located about 57 million light-years away. NGC 4564 crossed the meridian at 22:25 PDT on May 12th but it is still a bit light then at this time of year so waiting another hour is a better time to observe it.
Our Observing Director, Robert Conrad, and I have teamed up to bring you an observing challenge in preparation for Astronomy Day. You can win a prize too and if you need hints, we will provide a hint each day for the next few days. See all the details below. Good luck!
Checkout the latest hints – all the hints have now been provided!
The image below includes at least 15 galaxies but can you identify the galaxy in the yellow circle and when would be an good time observe it on Astronomy Day (May 12th, 2018)?
You can get help in tackling this challenge by attending Robert’s presentation on using using Stellarium and locating objects at Astronomy Day. Additional clues will follow in the next few days. Send your answers to firstname.lastname@example.org or email@example.com. Participants who correctly identify the the galaxy will be eligible to win a special edition of “Atlas of the Stars”, published every 10 years, in a draw following Robert’s 2-3pm presentation on Astronomy Day.
Hints (two more coming in the next few days)
The field of view in the image is approximately 3.4 by 2.3 degrees and the same field is visible during most of the night on May 12th from Vancouver. That is not much to go on but look for further hints over the next few days.
Asteroid Kalliope (magnitude 11) passes through the bottom left hand side of this field from May 3rd to May 12th, 2018.
The image includes parts of the Virgo Galaxy cluster.
The final hint is that the image contains several Messier objects including M58, M59, M60, M87, M89.
