Astronomers watching the repeated and drawn-out dimming of a relatively nearby Sun-like star have interpreted their observations to indicate an eclipse by a gigantic exoplanet’s complex ring system, similar to Saturn’s except much, much bigger. What’s more, apparent gaps and varying densities of the rings imply the presence of at least one large exomoon, and perhaps even more in the process of formation!

ROCHESTER, N.Y., Jan. 26 (UPI) — A new study, published this week in the Astrophysical Journal, details a planet with rings that put the halos of Saturn and Jupiter to shame.

Wonderful news! Asteroid 2004 BL86, which passed closest to Earth today at a distance of 750,000 miles (1.2 million km), has a companion moon. Scientists working with NASA’s 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of the asteroid which show the tiny object in orbit about the main body.
While these are the first images of it, the “signature” of the satellite was seen in light curve data reported earlier by Joseph Pollock (Appalachian State University, North Carolina) and Petr Prave (Ondrejov Observatory, Czech Republic) according to Lance Benner who works with the radar team at Goldstone.
2004 BL86 measures about 1,100 feet (325 meters) across while its moon is approximately 230 feet (70 meters) across. The asteroid made its closest approach today (Jan. 26th) at 10:19 a.m. (CST), however it will peak in brightness this evening around 10 p.m. (4:00 UT) at magnitude +9.0. Unlike some flybys, 2004 BL86 will remain within a few tenths of a magnitude of peak brightness from 6 p.m. tonight (CST)
The United States Constitution does not allow ‘preventive detention’ — a much abused 18th century prerogative of royal power that was abhorrent to our founding fathers. We are meant to be a country of law, not arbitrary state power. No imprisonment on suspicion that someone might commit a crime and no keeping someone in prison beyond his allotted sentence just because someone thinks he might still be dangerous
Sexually Violent Predator laws in 20 states are an exception. Indefinite preventive detention in a psychiatric facility (really a prison in all but name) is permitted if the individual has committed a violent sexual crime and has a mental disorder that predisposes to its repetition. The US Supreme Court in a narrow 5-4 decision found this to be constitutional, but explicitly only if the perpetrator has a definite mental disorder that would distinguish him from the much more common opportunistic criminal rapist. No mental disorder, no preventive detention.
In an attempt to facilitate preventive detention under SVP commitment statutes, many state evaluators blatantly misused the inherently unreliable Paraphilia Not Otherwise Specified as a qualifying diagnosis in cases that involved no more than typical, opportunistic rape. Until recently, juries bought it — unjustly committing common
