A September Morning Sky
The Moon, three planets, and a bright star gathered near the ecliptic plane in the September 18 morning sky over Veszprem Castle, Hungary. In this twilight skyscape, Mercury and Mars still shine close to the eastern horizon, soon to disappear in the glare of the Sun. Regulus, alpha star of the constellation Leo, is the bright point next to a waning crescent Moon, with brilliant Venus near the top of … Read More →
[NASA] Suomi NPP Satellite Captures Thermal Image of Hurricane Maria
The VIIRS instrument on NASA-NOAA’s Suomi NPP satellite captured a thermal image of Hurricane Maria on Sept. 20 at 2:12 a.m. EDT. The image showed very cold cloud top temperatures in the powerful thunderstorms in Maria’s eyewall. Maria’s eye was just east of the American Virgin Islands, and its northwestern quadrant stretched over Puerto Rico. via NASA http://ift.tt/2xn5mNK
[NASA] Northern Lights Over Canada
The spectacular aurora borealis, or the “northern lights,” over Canada is sighted from the International Space Station near the highest point of its orbital path. The station’s main solar arrays are seen in the left foreground. This photograph was taken by a member of the Expedition 53 crew aboard the station on Sept. 15, 2017. via NASA http://ift.tt/2xNXbeZ
Veil Nebula: Wisps of an Exploded Star
Wisps like this are all that remain visible of a Milky Way star. About 7,000 years ago that star exploded in a supernova leaving the Veil Nebula. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to people living at the dawn of recorded history. Today, the resulting supernova remnant, also known as the Cygnus Loop, has faded and is now … Read More →
[NASA] Long Way From Home
This picture of a crescent-shaped Earth and Moon – the first of its kind ever taken by a spacecraft – was recorded Sept. 18, 1977, by NASA’s Voyager 1 when it was 7.25 million miles (11.66 million kilometers) from Earth. The moon is at the top of the picture and beyond the Earth as viewed by Voyager. via NASA http://ift.tt/2fe9adV
Cassini s Final Image
As planned, the Cassini spacecraft impacted the upper atmosphere of Saturn on September 15, after a 13 year long exploration of the Saturnian System. With spacecraft thrusters firing until the end, its atmospheric entry followed an unprecedented series of 22 Grand Finale dives between Saturn and rings. Cassini’s final signal took 83 minutes to reach planet Earth and the Deep Space Network antenna complex in Canberra Australia where loss of … Read More →

100 Steps Forward
A beautiful conjunction of Venus and Moon, human, sand, and Milky Way is depicted in this night skyscape from planet Earth. The scene is a panorama of 6 photos taken in a moment near the end of a journey. In the foreground, footsteps along the wind-rippled dunes are close to the Huacachina oasis in the southwestern desert of Peru. An engaging perspective on the world at night, the stunning final … Read More →
