    Bad idea. Iron kills the sun. It's the reason massive star dies, when the element starts fusing into iron, that's it. Iron absorb energy which basically saps the nuclear power of the star's core and stops the convection pressure, allowing gravity to win over and collapse the star.

    also the gravity the sun can produce would suck our little probes in and never let go.

    From what I understand, the fusion reaction fueling the sun converts the (H) and (He) atoms into iron and other heavy elements, which slowly sink to the core and increase the mass of the sun. Once it reaches critical mass and goes into gravitational collapse, it turns into a super nova.

    It's not about reaching critical mass, it's about running out of fuel. No fuel, no pressure against gravity.

    The image above, seen in EUV, shows a brief snapshot of the event with the column of solar plasma stretching nearly as far as the distance between Earth and the Moon.

    Magnetic forces pulled back and forth a long arch of plasma (known as a “prominence”) during the week of July 10-16, 2014.

    NASA's EUNIS sounding rocket mission spotted evidence (nanoflares) to explain why the sun's atmosphere is so much hotter than its surface.

    A very long filament hung across the sun's surface for over a week from July 31 to Aug. 6.

    Filaments consist of clouds of cooler gas raised above the sun's surface by magnetic forces. Normally they exhibit a great deal of instability and break apart in days or even hours.

    On Sept. 10, 2014, the Sun unleashed a massive X1.6-class solar flare aimed directly at Earth. Take a look at amazing photos of the solar storm
