On Jan. 9, 2003, Australian officials found the Taiwanese ship High Aim 6 adrift off the West Australian coast. It had plenty of fuel, and the crew’s personal belongings were still aboard (including seven toothbrushes), but it was mysteriously empty, drawing comparisons to the Mary Celeste of 1872.

Authorities spent two days inspecting the vessel and conducted an aerial search of 7,300 square nautical miles, but they found no trace of the crew, who had last contacted the owners on Dec. 13 from the Marshall Islands, halfway between Papua New Guinea and Hawaii.

That’s all. The unwanted ship was finally sunk to serve as a fish habitat, but no one knows what happened to the crew.

A “sea-monster” reported by the officers and crew of H.M.S. Osborne in calm waters off northern Sicily, June 2, 1877. These sketches were produced by Lt. Haynes, a witness, for the London Graphic.

A Lt. Osborne told the New York Independent that the row of fins pictured in the first sketch was 30 to 40 feet long. The second sketch, he said, shows the creature “end on,” depicting only the head, which was “bullet-shaped and quite six feet thick,” and flippers. Osborne estimated that the animal was 15 or 20 feet wide across the back, and “from the top of the head to the part of the back where it became immersed I should consider about fifty feet, and that seemed about a third of its whole length.”

“Thus it is certainly much longer than any fish hitherto known to the zooelogists,” concludes the Independent, “and is, at least, as remarkable a creature as most of the old wonder-makers ever alleged.”

French astronomer Camille Flammarion writes of a curious optical phenomenon in Wonders of Earth, Sea And Sky (1902):

Ulloa, being in company with six fellow-travellers upon the Pambamarca at daybreak one morning, observed that the summit of the mountain was entirely covered with thick clouds, and that the sun, when it rose, dissipated them, leaving only in their stead light vapors, which it was almost impossible to distinguish. Suddenly, in the opposite direction to where the sun was rising, “each of the travellers beheld, at about seventy feet from where he was standing, his own image reflected in the air as in a mirror. The image was in the centre of three rainbows of different colors, and surrounded at a certain distance by a fourth bow with only one color. … All these bows were perpendicular to the horizon; they moved in the direction of, and followed, the image of the person they enveloped as with a glory.”

“The most remarkable point was that, although the seven spectators were standing in a group, each person only saw the phenomenon in regard to his own person, and was disposed to disbelieve that it was repeated in respect to his companions,” Flammarion writes. “The same apparition was observed in the polar regions by Scoresby, and described by him. He states that the phenomenon appears whenever there is mist and at the same time shining sun.”
