L2 is ideal for astronomy because a spacecraft is close enough to readily communicate with Earth, can keep Sun, Earth and Moon behind the spacecraft for solar power and (with appropriate shielding) provides a clear view of deep space for our telescopes

L2 is the second Lagrange point in the Earth-Sun system. It’s located 1.5 million kilometers behind Earth, as seen from the Sun. L2 is a good place to observe the universe because it orbits the Sun at the same rate as Earth.

L2 is one of five Sun-Earth Lagrange points. At these points, the gravitational forces of the Sun and Earth are roughly equal, creating a stable orbital location. This allows small objects in the region to have the same orbital period as Earth. 

L2 has been home to the following spacecraft: 

• WMAP 
• Planck 
• James Webb Space Telescope 

A space station at L2 has been designed, with budgets for power, mass, and overall cost. The design also includes an analysis of risks and how they could be mitigated.

The James Webb Space Telescope is located at the second Sun-Earth Lagrange point, or L2. L2 is about 1.5 million kilometers (1 million miles) from Earth.  The telescope will orbit the Sun in a halo orbit around L2.  The telescope’s large sunshield protects it from the Sun, Earth, and Moon’s light and heat.  

Other objects at Lagrange points include: 

• Deep Space Climate Observatory (DSCOVR): 
• Advanced Composition Explorer (ACE): 
• LISA Pathfinder (LPF): 
• Solar and Heliospheric Observatory (SOHO):

New ideas in space exploration come from all corners, and, by and large, the community welcomes anybody interested in the field. Having just read A City on Mars, it seems that even people who disagree with the idea that the age of space settlement is imminent will be accepted into the fold by enthusiasts. Now, a new entrant has joined – Daniel Akinwumi is a Nigerian graduate student at the University of Strathclyde who recently published his Master’s thesis detailing the design of the “intergalactic hub,” or I-HUB.

The Intergalactic Hub (I-HUB) is a proposed space settlement designed by Daniel Akinwumi. The I-HUB is a space station at Sun-Earth L2

Here are some other intergalactic hubs: 

• The Intergalactic Trade hub of Gann-Dellbert: This hub features intergalactic delegates trading resources, planets, and possibly populations. 
• Royale High Intergalactic Trading Hub: This hub has a wallpaper available for download.
