article_snippet.sent: Two strange, bright flashes on the surface of dwarf planet Ceres may have different origins, according to new infrared images released by Nasa.
article_snippet.sent: new infrared images released by Nasa were revealed as part of the first colour map of dwarf planet Ceres, showing variations in surface materials, and revealing the diverse processes that helped shape it.
article_snippet.sent: dwarf planet Ceres may appear to be a drab, grey world, but new infrared images suggest there is more to the dwarf planet than first thought.
article_snippet.sent: Images taken using blue (440 nanometers), green (550 nanometers) and infrared (920 nanometers) spectral filters were combined to create the first colour map of Ceres . '
article_snippet.sent: The 'alien' spots on the surface, named feature 1 and feature 5, show up in visible light images as bright flashes in comparison to the rest of dwarf planet Ceres's surface.
article_snippet.sent: the images show the full range of different crater shapes that can be found at Ceres surface: from shallow, flattish craters to those with peaks at those with peaks at their centers centers .
article_snippet.sent: The origins of Ceres bright spots, which have captivated the attention of scientists and the public alike, remain unknown. '
article_snippet.sent: The glimmers of light are visible even when The glimmers of light are near the edge of Ceres, suggesting that The glimmers of light must be high above the surface rather than at the bottom of an impact crater, as previously believed. '
article_snippet.sent: The glimmers of light are visible even when The glimmers of light are near the edge of Ceres, suggesting that are on a high elevation in relation to the rest of the surface .
article_snippet.sent: He noted that at dawn on Ceres, the spots shine brightly, but fade as dusk draws in.
article_snippet.sent: Ceres is the bright spot in the centre of the image.
article_snippet.sent: The long exposure made Ceres appear overexposed, and exaggerated Ceres size
article_snippet.sent: A cropped, magnified view of Ceres appears in the inset image at lower left .
