Earth will have a second moon orbiting the planet when it grabs a tiny astroid in its gravitational pull later this month, according to a new study.
The big picture: The "mini-moon" will be around from Sept. 29 until Nov. 25, following a horseshoe path before returning to its home in an asteroid belt orbiting the sun, per the study, published in the September edition of the The Research Notes of the AAS journal.
Scientists sent hundreds of critically endangered corals from South Florida to the Texas Gulf Coast on Wednesday in a research and restoration project.
Why it matters: Last year's severe marine heatwave caused corals in the Florida Keys to expel algae that lives in their tissues, turning them white in a widespread coral bleaching event. Many of these corals, which are havens for biodiversity, were wiped out.
