11:30 AM | The King and Queen of Planets
Right now, two planets dominate the sky after sunset: Venus in the west, and Jupiter high to the south. Both are amazingly bright, clearly ruling their areas of the sky. Both planets are also in parts of their orbits where they’re relatively close to Earth, providing excellent viewing opportunities. Danish “amateur” astronomer (and frequent BA contributor) Emil Kraaikamp took full advantage of this, using his custom-made 40-centimeter Dobsonian telescope to take images of the […]

7:00 AM | Sol 962: MAHLI wheel imaging
  by Ken Herkenhoff The Sol 960 drive went as planned, for a total of over 102 meters!  The rover has driven far enough since the last full set of MAHLI images were acquired that it’s time to take another full set to look for more wheel wear.  So my focus today as MAHLI/MARDI uplink lead was on planning wheel images.  MARDI images are typically taken at each wheel-imaging position …

4:00 AM | A1689-zD1, una galassia matura nell’Universo primordiale
Grazie ad una serie di osservazioni realizzate con il Very Large Telescope’s X-shooter dell’ESO e il radiotelescopio ALMA, un gruppo di astronomi ha osservato una delle galassie più giovani e più remote mai identificate. Denominata con la sigla A1689-zD1, si tratta di un oggetto scoperto nel Febbraio del 2008, mediante osservazioni basate sul redshift fotometrico, ed è … Continue reading A1689-zD1, una galassia matura nell’Universo […]

8:45 PM | Accelerating Universe ? — Not so Fast
Maybe the rush to embrace an Accelerating Universe and Dark Energy was a bit too hasty. New analysis shows that the rulers used to measure Supernova 1A brightness curves were unknowingly measuring two different types of Supernova 1As (1) with … Continue reading →

7:44 PM | The Lives of the Longest Lived Stars
Heavy stars live like rock stars: they live fast, become big, and die young. Low mass stars, on the other hand, are more persistent, and live longer. Fusing hydrogen slow and steady wins the stellar age-race.

11:00 AM | BA Video: An Electrifying Volcano
In the Mexican state of Colima there lies an active volcano. Actually, Mexico is lousy with volcanoes, but this one has been doing more than its share of rumbling and grumbling lately. Photographer César Cantú went to the Colima volcano to photograph it recently, and what he got was way more than he hoped for: huge lightning discharges blasting through the ash cloud! This type of event is well-known, but not terribly well-understood. I do love a scientific mystery, which is why […]
