Exploring The Universe: 20 Astronomy Questions To Test Your Cosmic IQ. Gerda K. January 2, 2025 at 4:33 AM.
The youngest of these stars are several million years old. [5] A 40-page comic and associated promotional offers about HsV and the story surrounding it were presented at the 24th Dragon Con in Atlanta on 3 September 2010, as well as first pictures of HsV from the Hubble Space Telescope. [6] [7] [8] The launch was streamed live on UStream. [8]
Based on the 2013 data, the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. On 5 February 2015, new data was released by the Planck mission, according to which the age of the universe is 13.799 ± 0.021 billion years old and the Hubble constant was measured to be 67.74 ± 0.46 (km/s)/Mpc.

The amount of shift is quite small, even for the nearest stars, measuring 1 arcsecond for an object at 1 parsec's distance (3.26 light-years), and thereafter decreasing in angular amount as the distance increases. Astronomers usually express distances in units of parsecs (parallax arcseconds); light-years are used in popular media.
An echo of ShaSS 073 galaxy's light detected by ESO's VLT Survey Telescope. The ShaSS 622-073 system is composed of the larger galaxy ShaSS 073 (seen in yellow in the image on the right) and the smaller galaxy ShaSS 622 (seen in blue) that are at the very beginning of a merger.
NGC 3532; Observation data (J2000 epoch); Right ascension: 11 h 05 m 33 s [1]: Declination: −58° 43.8′ [1] Distance: 1,321 [2] ly (405 pc): Physical characteristics; Other designations: NGC 3532, [1] Caldwell 91, Cr 238, Mel 103, C 1104-584, Cl* 1104-584, CL 1104-584, Lacaille II.10, [3] Football Cluster, Wishing Well Cluster [4] [5] [6] [7]
The proposed EChO instrument on SPICA (SPEChO) is a spectrometer covering light wavelengths from 5 to 20 micrometres, and will observe exoplanet atmospheres utilizing transit spectroscopy. [ 6 ] [ 7 ] As long with a potential to recover the original scientific goals from EChO, SPEChO will enable SPICA to conduct specialized exoplanetary science ...
BPM 37093 was first observed to be a pulsating variable in 1992, [1] and in 1995 it was pointed out that this yielded a potential test of the crystallization theory. [9] In 2004, Antonio Kanaan and a team of researchers of the Whole Earth Telescope estimated, on the basis of these asteroseismological observations, that approximately 90% of the ...
