Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                   Evidence of an Active Volcano on Venus

   Explanation: Are volcanoes still active on Venus? More [10]volcanoes
   are known on Venus than Earth, but when [11]Venusian volcanoes last
   erupted is not directly known. [12]Evidence bolstering very recent
   volcanism on Venus has recently been uncovered, though, right here on
   Earth. [13]Lab results showed that images of [14]surface lava would
   become dim in the infrared in only months in the dense Venusian
   atmosphere, a dimming not seen in ESA's [15]Venus Express images. Venus
   Express entered orbit around [16]Venus in 2006 and [17]remained in
   contact with Earth until 2014. Therefore, the [18]infrared glow (shown
   in false-color red) recorded by Venus Express for [19]Idunn Mons and
   featured here on a NASA [20]Magellan image indicates that this volcano
   erupted very recently -- and is still active today. Understanding the
   [21]volcanics of [22]Venus might lead to insight about the
   [23]volcanics on Earth, as well as [24]elsewhere [25]in [26]our
   [27]Solar System.
