Woodgate notes that the finding doesn't preclude the possibility that electron beams also carry some of the energy unleashed by magnetic activity But the observations hint that protons serve as the dominant energy carrier in AU Microscopium
- and perhaps in other stars, including the sun.
Their orbital inclinations are 15[degrees] and 11[degrees], respectively, which is why Ceres crosses such non-zodiacal constellations as Piscis Austrinus and Microscopium
. The average inclination of the first 300 numbered asteroids is 8[degrees].
His air pump (Antlia) and furnace (Fornax) reflect investigations of experimental science, and the microscope (Microscopium
) also salutes scientific study.

His constellations read like a Who's Not Who list of the southern sky: Antlia Pneumatica, the Air Pump; Caelum, the Engraving Tool; Circinus, the Geometer's Compasses; Fornax Chemica, the Chemist's Furnace; Horologium Oscillatorium, the Pendulum Clock; Mons Mensae, Table Mountain, which overlooked Lacaille's observatory; Microscopium, the Microscope; Norma et Regula, the Level and Square; Octans, the Octant; Pictor, the Painter's Easel; Pyxis Nautica, the Ship's Compass; Reticulum Rhomboidalis, the eyepiece reticle with which Lacaille measured star positions; Sculptor, the Sculptor's workshops; and Telescopium, the Telescope.
Appropriately, Lacaille 8760 graces a constellation that Lacaille invented, and one that's dim even by his standards: Microscopium. Even among hard-core observers, few have ever seen Microscopium; its brightest star is only 5th magnitude.
Lalande 21185 is the third brightest red dwarf in the sky, topped only by Lacaille 8760 and Lacaille 9352 in Microscopium's neighboring constellation, Piscis Austrinus.
Then I turned to the southern constellations peeking over the horizon, picking out the stars of Grus, Phoenix, and Microscopium
. The names seemed foreign to me, like some other sky of some other planet.
This is the dark realm of Microscopium
(and a little-known part of Sagittarius).

Woodgate (NASA-Goddard Space Flight Center) and his colleagues turned the Hubble Space Telescope toward the flare star AU Microscopium. This red dwarf produces outbursts that put solar flares to shame, sometimes doubling the star's overall brightness in the ultraviolet part of the spectrum.
Woodgate's team monitored AU Microscopium with Hubble's Goddard High Resolution Spectrograph, recording spectra at the rate of once every 0.4 second for 3 1/2 hours.
