Article is a bit breathless.

> and can be viewed using a microscope capable of 1000x magnification—a technology that has been available for hundreds of years.

I don't think so; maybe 100 years. To achieve 1,000x magnification with an optical microscope, you need oil (or some other fluid with a refractive index similar to that of the lens) between the objective lens and the subject.

I believe the maximum theoretical magnification you can achieve with an optical microscope is about 1,400x. The limit is imposed by the minimum wavelength of visible light.

"tardigraves find a way."

wikipedia:

They have been found in diverse regions of Earth's biosphere – mountaintops, the deep sea, tropical rainforests, and the Antarctic. Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life. Tardigrades have survived exposure to outer space.
