Young suns still lie within dusty NGC 7129, some 3,000 light-years away toward the royal constellation Cepheus. While these stars are at a relatively tender age, only a few million years old, it is likely that our own Sun formed in a similar stellar nursery some five billion years ago.
Most noticeable in the sharp image are the lovely bluish dust clouds that reflect the youthful starlight. But the compact, deep red crescent shapes are also markers of energetic, young stellar objects. Known as Herbig-Haro objects, their shape and color is characteristic of glowing hydrogen gas shocked by jets streaming away from newborn stars. Paler, extended filaments of reddish emission mingling with the bluish clouds are caused by dust grains effectively converting the invisible ultraviolet starlight to visible red light through photoluminesence.
Ultimately the natal gas and dust in the region will be dispersed, the stars drifting apart as the loose cluster orbits the center of the Galaxy. At the estimated distance of NGC 7129, this telescopic view spans about 40 light-years.

“Here’s an excuse to stay outside tonight that doesn’t (necessarily) involve any drunken shenanigans: according to Accuweather, we may be able to see a display of the northern lights over the city Saturday! They write: “The [solar] flare is also expected to cause vibrant northern lights from the Arctic as far south as New York, the Dakotas, Washington and Michigan, with a smaller possibility of it going into Pennsylvania and Iowa, even Kansas.” — Accuweather
A solar flare that occurred around 2 a.m. Thursday morning may create a spectacular display of northern lights Saturday evening. The midlevel flare had a long duration and was directed at Earth. According to AccuWeather.com Astronomer Hunter Outten, who stated that this flare was “impressive”, these are the best conditions for seeing a direct effect on our planet. On the Kp index, the flare has been categorized at 6 to 8. This is a scale for measuring the intensity of a a geomagnetic storm. The 6 to 8 rating means that the effects of the radiation will have a greater reach.
The radiation from such a flare may cause radio wave disturbances to electronics such as cell phones, GPS and radios, causing services to occasionally cut in and out. While traveling slower than was originally anticipated, the flare effects are moving towards Earth at 1000 km per second.
The flare is also expected to cause vibrant northern lights from the Arctic as far south as New York, the Dakotas, Washington and Michigan, with a smaller possibility of it going into Pennsylvania and Iowa, even Kansas. The lights are currently estimated for 8 p.m. EDT Saturday arrival, with a possible deviation of up to seven hours. If the radiation hits much after dark settles on the East Coast the lights may be missed and will instead only be visible for the West.
Solar flares create auroras when radiation from the sun reaches Earth and interacts with charged protons in our atmosphere. The effects are greater at the magnetic poles and weaken as they move south from the Arctic or north of the Antarctic. In the northern hemisphere the results are called the aurora borealis, with the aurora australis being its southern counterpart. The result is a spectacular display of light and color for areas with clear enough views.
Reminder: The Amateur Astronomy Association of NY is hosting a starfest event and will be located in great viewing conditions (unless it rains or gets too cloudy) for the aurora as well.
