Indirect observations have by now mostly proven the existence of black holes as predicted in Einstein's theory of relativity.

The math behind the theory also, however, provides for the existence of white holes, something that has never been seen before.

White holes are the hypothetical opposites of black ones, and general relativity implies white holes must be somewhere in the universe too.

The problem for astronomers is that no one has been able to find one yet and no one is exactly sure what they are looking for.

If correct, white holes would be time-reversed black holes from which particles can only escape and never return.

The search for the universe's missing white holes has focused on the possibility they exist as massive explosions like gamma-ray bursts...

Each probe carried three instruments designed to test for microbe signatures, including one called the Labeled Release [LR] apparatus.

Radioactive tags were added to the solution to allow for the detection of any gases released by reactivated microbes.

Given that the first two instrument suites returned negative, scientists were shocked when the LR returned positive in readings.

Immediately after applying nutrients to the soil, methane gas was detected as evidence that something alive metabolised the solution.

Both probes produced the same results, but NASA scientists resisted the discovery, lacking confirmation from the other instruments.

Tantalising hints, however, suggest Viking may have been on to something, including the later detection of atmospheric methane.

More than 100,00 "Kuiper Belt objects" at least 62 miles [100 km] in diameter float in the belt to the edge of a mysterious void.

Solar System models do not explain how the planet could exist, but it is possible the sun could of captured it from another star.
