For all planet hunters out there From the start of the month Jupiter’s position just keeps getting better and better. At the start of the month it rises about 5:30 in the very early evening […]
Observing the transit of Venus was no easy task, it required careful observations and measurement. 250 years ago expeditions went out across the world to measure this amazing and rare event in order to help us understand the size of the known universe.
James Cook’s voyage to Tahiti in 1769 was the culmination of 130 years of work to observe and understand the Transit of Venus. Edmund Halley was instrumental in laying the foundations for the successful observations in 1769 and ultimately solving the Earth – Sun distance.
In New Zealand, Space Starts with Sheep; a new season is about to open for exoplanets as scientists discover an efficient method to predict microlensing; Earth’s Moon to be used as a giant radio telescope; “Hello, Andromeda calling”, gravitational waves might be used to carry information; 1500 km long water cloud appears on Mars after the planet-wide storm from last month, while InSider probe has only one month left hurling through space, and will land on Mars in November; scientists narrow down the landing sites for Mars 2020 rover; change of plans, why not land among the clouds of Venus? Hubble and Chandra telescopes have been repaired, mostly by switching them on and off and stay tuned for the position of Uranus in the sky.
Riding on Elon Musk’s muscle power earthlings are preparing to invade the Moon again. There they will find that some of its craters have been renamed to honour the Apollo 8 mission, the first to orbit our natural satellite 50 years ago. Venus is hailed by the Parker Solar probe that swings by it, Jupiter’s Moon Europa has 15 meters ice spikes on the surface and Saturn’s rings are not just water nor all the lost airline luggage. Mars has to resign to the idea that earthlings have figured out how to grow plants on it. Not even perchlorates can stop them. And last but not least, New Horizons is unstoppable going towards Ultima Thule.
It’s the Winter of the Planets and in the early evening this week you can see Mercury, Venus, Jupiter, Saturn and Mars. Then there is the Lunar Eclipse on Saturday morning as well.
Next year is the 250th anniversary of James Cook’s voyage to the Pacific Ocean. One the things he did was contribute to a more accurate calculation of the distance between the Earth and the Sun by observing the transit of Venus.
The Winter of planets continues with Jupiter, Saturn and Mars all at fantastic high positions over the week. Venus is also getting a bit higher out of the distorted atmosphere near the horizon.
The night sky this week has a few treats including the asteroid Vesta, Mars and the Moon getting close, Jupiter’s moons crossing the planet and the fantastic nebulae in Sagittarius showing off.
The night sky this week will be dominated by the Moon, so it’s a good time to get out and appreciate the planets that are getting into a more favourable position for viewing.
Ian Cooper is a giant in New Zealand astrophotography. He has been capturing the night sky since the 1970s and in this article he takes us through some of the highlights and give us some tips.
The week in space includes the launch of the Falcon 9 Block 5 rocket, the planned helicopter for Mars and the BepiColombo mission is getting closer to launch.
In the 1960s and 1970s the Soviet Union and the United States launched a number of spacecraft to Venus that greatly increased our understanding of Earth’s twin.
Venus doesn’t capture a lot of press time as it’s often overshadowed by the more hospitable Mars and the more photogenic planets of Saturn and Jupiter. It’s not all quiet around Venus, as JAXA has Akatsuki orbiting Earth’s twin and sending back some great images and building our understanding of Venus.
TESS was launched on a Falcon 9 rocket from SpaceX on 18 April. The satellite will survey the whole sky to look for exoplanets that transit their stars.
NASA’s Parker Solar Probe is set for launch on 31 July to begin it’s journey to the Sun’s corona to help us understand more about the solar wind and why the corona is so hot.
