In quantum mechanics, the Heisenberg uncertainty principle states precise inequalities that constrain certain pairs of physical properties, such as measuring the present position while determining future momentum; both cannot be simultaneously done to arbitrarily high precision. That is...

Title: The meteorite from Lake House Authors: C.T. Pillinger, J.M. Pillinger, R.C. Greenwood, D. Johnson, A.G. Tindle, A.J.T. Jull and M. Ashcroft. In 1991 a very big meteorite (>60kg, dimensions: diameter 50cm x height 40cm) was brought to the Natural History Museum by the then occupier of La...

Planets Can Form in the Galactic Center At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. Stars crowd each other as they whiz through space like cars on a rush-hour freeway. Supernova explosions blast out shock waves and bathe the region in intens...

Title: First Interstellar HCO^+ Maser Authors: Nicholas S. Hakobian, Richard M. Crutcher A previously unseen maser in the J = 1 - transition of HCO^+ has been detected by the Combined Array for Millimetre-wave Astronomy (CARMA). A sub-arcsecond map was produced of the 2 arcmin^2 region around DR...
