We won’t have a total solar eclipse again this year, but there are a three partial solar eclipses and two total lunar eclipses that will be viewable in various places from around the world.
- 31 January – total lunar eclipse visible from Australia, North America, eastern Asia and the Pacific Ocean
- 15 February – partial solar eclipse visible from part of Antarctica, Chile and Argentina
- 13 July – partial solar eclipse visible from Antarctica and the southernmost tip of Australia
- 27 July – total lunar eclipse visible from most of Europe, Africa, western and central Asia, and western Australia
- 11 August – partial solar eclipse visible in northeast Canada, Greenland, northern Europe and northeast Asia
That’s pretty much everyone, so mark the date of your eclipse in the calendar and get ready.
2. Meteor showers
Every year, there are a number of meteor showers, and if you get out there with a camera, you can grab some spectacular photos.
Two of the best ones to look out for are the Perseids, which will be peaking 12-13 of August with up to 60 meteors per hour, and the Geminids, which will be peaking 13-14 December with up to 120 meteors per hour.

3. We may finally see a black hole’s event horizon
In April this year, a multi-telescope project called the Event Horizon Telescope made a no-holds-barred attempt to photograph the event horizon of a black hole – not the black hole itself, but the point of no return, where the pull of the object is so strong that nothing, not even light, can escape.
We’re still waiting to see what they photographed over five nights of observation time of Sagittarius A*, the black hole at the centre of our galaxy, and hopefully that image will drop sometime in early 2018. We’re so excited, for real.
4. Moon exploration forays
It is (maybe not quite) official: Earthlings are going back to the Moon. The last person to set foot on its surface was NASA astronaut Eugene Cernan in 1972, and next year, well, we may not get back there personally, but there’s a whole bunch of nifty Moon stuff percolating.
For starters, India is putting a rover on the Moon for the first time in the country’s history in 2018, and that’s rad.
SpaceX also said it’s planning a trip to lunar orbit – with two private citizens on board (although it’s been pretty quiet about it for a while). China’s Chang’e 4 and Chang’e 5 are going to be conducting a dark side exploration and sample return mission respectively.
There have also been rumblings of the US sending humans back to the Moon, and don’t forget Google’s Lunar XPrize – a competition for private entities to put a robotic rover on the Moon.
5. Asteroid science
Were you excited about Rosetta and Philae and their rendezvous with and subsequent research on Comet 67P/Churyumov-Gerasimenko?
We have not one, but two asteroid landers due to meet their targets this year.
In June, JAXA’s Hayabusa 2, which launched in 2014, is going to meet up with asteroid Ryugu, a near-Earth asteroid with a rare combination of both C-type and G-type qualities.
And in August, NASA’s OSIRIS-REx is going to meet up with near-Earth asteroid Bennu.
6. Pulsar fireworks
Sometime early next year – it’s hard to say exactly when – a pulsar is going to fly really, really closely past one of the brightest stars in our galaxy, through the disc of gas and dust surrounding an extremely luminous blue star 15 times the mass of the sun and 10,000 times brighter.
When that happens, there’s going to be an explosion of astrophysical fireworks that will help researchers measure the mass, gravity, magnetic field, stellar wind and disc properties.
7. There’s going to be a Mercury probe
This year we saw the end of Cassini’s mission. Juno is out there studying Jupiter, but we definitely need more planetary probes. Luckily we’re going to get ’em.
In 2018, the ESA and JAXA are launching their joint mission – BepiColombo, which is going to probe Mercury, our Solar System’s closest planet to the Sun.
OK, granted it’s not actually going to reach Mercury until 2025, but still, it gives us a lot to look forward to – and reminds us that, when it comes to space, there is always something out there to look forward to seeing.
