L’hanno apostrofata come parassita, una galassia distante fotografata da Hubble mentre inizia a essere oscurata dal passaggio di una stella simile al giovane Sole. In realtà, la sua fortuita presenza permetterà di svelare in controluce

Candidate most massive binary star identified - Astronomers have observed a binary star that potentially weighed 300-400 solar masses at birth. The present day total mass of the 2 stars is x200-300 our Sun, depending on its evolutionary stage, which possibly makes it the most massive binary star known to date. R144 can be found in an outer area of the star-forming region 30 Doradus in the Large Magellanic Cloud. (Monthly Notices of the Royal Astronomical Society Letters).
