The century's longest total solar eclipse on land
On 2 August 2027, the Moon will completely cover the Sun along a path crossing Spain, North Africa, Egypt and western Saudi Arabia, including Jeddah and Makkah. Near Luxor in Egypt, totality will last about six minutes and 23 seconds, the longest total eclipse on land this century.

Artemis IV aims to land astronauts on the Moon
NASA plans Artemis IV in 2028 as the first crewed Moon landing since Apollo 17 in 1972. Astronauts would travel on the Orion spacecraft and descend to the surface near the lunar south pole in a SpaceX or Blue Origin lander. Space schedules often slip, so the date is a target, not a promise.

A total solar eclipse crosses Australia and New Zealand
On 22 July 2028, the Moon's shadow crosses Australia from the Kimberley in the northwest to Sydney in the southeast, then passes over New Zealand's South Island. Along the path, day will turn to twilight for several minutes. Sydney will see its first total solar eclipse in more than 150 years.

Asteroid Apophis passes close to Earth
On 13 April 2029, the asteroid Apophis, about 340 metres wide, will pass about 32,000 kilometres above Earth's surface, closer than many satellites. It poses no danger. It will be visible without a telescope from parts of Europe, Africa and Asia, and a NASA spacecraft will study it afterwards.

The International Space Station is retired
NASA and its partners plan to retire the International Space Station around the end of 2030 and guide it to a controlled re-entry over a remote part of the Pacific Ocean in 2031. Commercial space stations are being developed to take over its role in orbit.

Asteroid 2024 YR4 passes close to the Moon
On 22 December 2032, asteroid 2024 YR4, about 60 m wide, will pass about 21,000 km from the Moon's surface. Soon after its discovery, it briefly had a small chance of hitting Earth, which was ruled out in 2025. In March 2026, James Webb Space Telescope observations also ruled out a Moon impact. It poses no danger.

A total solar eclipse crosses China, Korea and Japan
On 2 September 2035, a total solar eclipse will sweep across northern China, including near Beijing, then the Korean Peninsula and central Japan, before heading out over the Pacific. Hundreds of millions of people live close to the path of totality.

LISA, an observatory for ripples in space, is due to launch
Around 2035, the European Space Agency, working with NASA, plans to launch LISA: three spacecraft flying in a triangle 2.5 million km on each side. Lasers between them will detect gravitational waves, tiny ripples in space-time from colliding giant black holes across the universe.

A great total solar eclipse crosses the United States
On 12 August 2045, a total solar eclipse will cross the United States from northern California to Florida, then continue over the Caribbean and South America. At its longest, the Sun will be hidden for more than six minutes, one of the longest total eclipses seen from the US.
- Mid-2061 · Predicted
Halley's Comet returns
Halley's Comet, which returns about every 76 years, will next pass closest to the Sun in mid-2061. Edmond Halley first predicted its return using Newton's laws in the 1700s. Its last visit was in 1986, so for many people alive today, 2061 will be their first chance to see it.

400 years of the Royal Observatory, Greenwich
On 22 June 2075, it will be 400 years since King Charles II founded the Royal Observatory at Greenwich. The line of longitude zero, the Prime Meridian, still runs through it, and the world's time zones are still counted from it.
- 10–11 December 2117 · Predicted
Venus crosses the face of the Sun
On 10 and 11 December 2117, Venus will pass directly between Earth and the Sun, appearing as a small black dot crossing the Sun's disc. These transits come in pairs more than a century apart. The last was in 2012, and the next after 2117 will be in December 2125.
- 2134 · Predicted
Halley's Comet returns again
After its 2061 visit, Halley's Comet will return again around 2134. Astronomers expect it to pass much closer to Earth than in 1986, which could make it a brighter sight in the night sky.
- Around 2178 · Predicted
Pluto completes its first orbit since its discovery
Pluto takes about 248 Earth years to travel once around the Sun. Discovered in February 1930, it will complete its first full orbit since its discovery around 2178, returning to roughly the same point in the sky where Clyde Tombaugh first spotted it.
- 16 July 2186 · Predicted
The longest total solar eclipse for thousands of years
On 16 July 2186, a total solar eclipse will darken the sky for up to about seven minutes and 29 seconds, near the coast of South America. Astronomers calculate it will be one of the longest total eclipses in thousands of years, close to the maximum length possible.

Mars comes closer to Earth than in nearly 60,000 years
In August 2003, Mars came closer to Earth than at any time in nearly 60,000 years. Astronomers calculate that this record will be beaten on 28 August 2287, when Mars will be slightly closer still and shine brightly in the night sky.
