05/15/2019 – Ephemeris – The bright planets this week

May 15, 2019 Comments off

Ephemeris for Wednesday, May 15th. Today the Sun will be up for 14 hours and 49 minutes, setting at 9:04, and it will rise tomorrow at 6:13. The Moon, 3 days before full, will set at 5:22 tomorrow morning.

Let’s look at the planets for this week. Mars will be in the western sky this evening, entering Gemini near Castor’s foot. It will set at 12:04 a.m. In the morning sky we have Jupiter, in Ophiuchus, which will actually rise at 11:09 tonight in the east-southeast. Jupiter won’t be considered an evening planet until it rises before sunset, which will occur after June 10th. Saturn will be next to rise at 1:04 a.m., also in the east-southeast. It’s in Sagittarius. Both planets are easily visible in as morning twilight grows. Venus will rise 53 minutes before the Sun in the east. It will remain in our morning sky, though too close to the rising Sun to be easily glimpsed. In August it will pass behind the Sun to enter the evening sky.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Let’s look at the planets for this week. Mars will be in the western sky this evening, above the V-shaped stars of the face of Taurus the bull. It will set at 12:18 a.m. In the morning sky we have Jupiter, in Ophiuchus, which will rise tomorrow at 12:39 a.m. in the east-southeast. Saturn will be next to rise at 2:27 a.m., also in the east-southeast. It is in Sagittarius. Tomorrow morning the Moon will be just right of the ringed planet. Venus will rise at 5:47 a.m. in the east. Venus will remain in our morning sky, though too close to the rising Sun to be easily glimpsed until August when it passes behind the Sun to enter the evening sky. It will be in position later this year to be our bright evening Christmas Star.

04/22/2019 – Ephemeris – Earth Day

April 22, 2019 Comments off

Ephemeris for Earth Day, Monday, April 22nd. Today the Sun will be up for 13 hours and 49 minutes, setting at 8:36, and it will rise tomorrow at 6:45. The Moon, 3 days past full, will rise at 12:24 tomorrow morning.

A good slogan for this Earth Day or any day is “Support your local planet.” As an amateur astronomer I look around the solar system at all the habitable planets. The Earth is it. Mars may be terraformed at great expense, that is made more earth-like. There may be life in the oceans of Jupiter’s moon Europa, or Saturn’s Enceladus, but they are not habitable for us. Terraforming (stopping and reversing climate change)  the Earth would be the easiest and much more practical. One look at our nearest neighbor Venus will show us our fate, hopefully in billions of years from now, a hell hole of heat and a crushing atmosphere. Our job is push-off that day as far as we can, and keep the Earth a blue-green oasis in the solar system.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Mars

Mars had its day, but that ended about 3 billion years ago. Being half the size of the Earth, Mars cooled down, lost its magnetic field, so the solar wind stripped away most of its atmosphere and water. Credit NASA.

Europa

Europa, one of the four Galilean moons of Jupiter and easily seen in small telescopes, is slightly smaller than our Moon. Under that thick icy shell lurks an ocean with more water than all the Earth’s oceans. There’s probably volcanic vents like the black smokers in Earth’s oceans where a whole ecology of extremophiles could live like they do on Earth. Credit: NASA.

Enceladus, a small moon of Saturn spews continuous geysers of water from cracks in its south polar region indicating an ocean below its frozen icy exterior. Sampling the plumes with the right instruments may detect life on this small world without the need for drilling. Credit: NASA.

Venus

Is this our future? Venus had the misfortune of ending up too close to the Sun. It has a hellish landscape of nearly 900 degrees F, and 90 times the Earth’s atmospheric pressure. Its clouds consist of sulfuric acid. Talk about a runaway greenhouse effect and acid rain… Credit: NASA.

04/17/2019 – Ephemeris – Let’s look for the bright planets

April 17, 2019 Comments off

Ephemeris for Wednesday, April 17th. Today the Sun will be up for 13 hours and 34 minutes, setting at 8:30, and it will rise tomorrow at 6:53. The Moon, 2 days before full, will set at 6:53 tomorrow morning.

Let’s look at the planets for this week. Mars will be in the western sky this evening, above the V-shaped stars of the face of Taurus the bull. It will set at 12:23 a.m. In the morning sky we have Jupiter, in Ophiuchus, which will rise tomorrow at 1:07 a.m. in the east-southeast. Saturn will be next to rise at 2:54 a.m., also in the east-southeast. It is in Sagittarius. Venus will rise at 5:56 a.m. again in the east-southeast. By 6:30 in the morning they will be strung out from the south down to the eastern horizon. Venus will remain in our morning sky, though more difficult to see until August when it passes behind the Sun to enter the evening sky. Tiny Mercury may be glimpsed a bit left and just below Venus in the bright twilight.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
