As you gaze up at the Christmas Moon, take note that NASA has a spacecraft currently orbiting Earth’s only natural satellite. NASA’s Lunar Reconnaissance Orbiter (LRO) mission has been investigating the Moon’s surface since 2009.
LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon.
Comet Lovejoy lived up to its name by releasing as much ethyl alcohol as in at least 500 bottles of wine every second as well as a type of sugar into space during its peak activity, according to new observations by an international team. The finding adds to the evidence that comets could have been a source of the complex organic molecules necessary for the emergence of life.
Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe’s existence, known as primordial black holes.
Nearly all black holes come in one of two sizes: stellar mass black holes that weigh up to a few dozen times the mass of our Sun, or supermassive black holes ranging from a million to several billion times the Sun’s mass. A team led by astronomers at the University of Maryland and NASA’s Goddard Space Flight Center has found evidence for a new intermediate-mass black hole about 5,000 times the mass of our star.
