In other religions, there was no need for astronomy except for the creation of the calendar. Ancient Pagans used Stonehenge to determine their calendar. In Early Judaism, they created their calendar. For Christianity, although it helped dictate holidays, it had pushback from philosophy and scientific observations. Astronomy played a major role in early Islam. Besides … Continue reading Ancient Achievements → Continue reading → Continue reading
Galileo Galileo Galilei (February 15, 1564 – January 8, 1642) made the telescope famous by improving upon spyglasses in order to increase their magnification and observe phenomena in space. He discovered that neither the sun nor the moon are smooth, observed the phases of Venus, and discovered the 4 biggest moons of Jupiter. Considering that … Continue reading Historical Astronomers in Context → Continue reading → Continue reading
We know that astronomers look to low-mass star systems for signs of life. But new research from NASA has indicated that these low-mass stars may emit substantial amounts of ultraviolet radiation during their lifetime, hindering if not eliminating the possibility of life on orbiting planets. Of course, astronomers look at terrestrial worlds that lie in … Continue reading Could Ultraviolet rays emitted by stars make planets uninhabitable? → Continue reading → Continue reading
Last week, a group of astronomers announced in Nature Astronomy that they had discovered the furthest star ever seen: a blue supergiant named Icarus that shone nearly 10 billion years ago, and located more than halfway across the universe. The astronomers were able to do this with the Hubble, and gravitational lensing. Per the lead author of … Continue reading Hubble Space Telescope Images the Most Distant Star Ever Observed → Continue reading → Continue reading
We all are familiar with the Galilean Moons; those 4 largest moons orbiting Jupiter which Galileo discovered with his telescope, and which were subsequently named after his lovers. Three of these moons (Io, Europa, Ganymede) have created auroral bursts in Jupiter’s atmosphere, but Callisto had only yielded two potential footprints … until last month! We know how … Continue reading Aurora Footprint of Jupiter’s Moons → Continue reading → Continue reading
NASA’s New Horizon’s spacecraft is only three months approaching Pluto, and for the first time, we have a true color picture of the Pluto/Charon dwarf planet system. As I sit here typing this, I say, “so what?” Well, it turns out that this is the first time that any spacecraft has traveled so long and […] Continue reading → Continue reading
NASA is currently assembling a group that it plans to call the Nexus for Exoplanet System Science (NExSS), which will be a group of specialists from various scientific fields in hopes to study the nature of exoplanets and figure out if some might be suitable for life. Currently the project has garnered support among planetary and […] Continue reading → Continue reading
