The nearest bit of the nebula, though, is a mere 1,200 light years away and the two radio telescopes can detect radio signals from a portion of it that is 8 light minutes (150m kilometres or 90m miles) across.
In a series of comments on Facebook which came to light minutes after his successful election on Friday, Mr Small apparently claimed that "migration from Muslim countries" led to the spread of TB in Britain, the Redditch Standard reported.
Mars is next, but its distance must be measured in light minutes, 13.2 light-minutes to be precise.
To put it into mind-boggling perspective, one light-minute is equal to a little more than 11 million miles, and despite this almost unfathomable distance, M-15 is still within the Milky Way.
"3 light-minutes at closest distance," Musk wrote.
Several users asked about problem of information exchange: often at more than 20 light-minutes away, Mars wouldn't be easy to browse the web from.
For example, at its farthest, Mars is about 20 light-minutes away from Earth, and even Pluto is only about 4 light-hours distant.
At a distance of about eight light-minutes, the most frequently studied star is the Sun, a typical main-sequence dwarf star of stellar class G2 V, and about 4.6 billion years (Gyr) old.
A second dose of UV light (1 minute) was applied to covalently link RGDS within the hydrogel.
These devices measures light every minute, and record the maximum light level at the end of every 10 minute period.
People can detect a flash of light as minute as a single photon, Scientific American reports.
