The conjunction of Venus and Jupiter was observed at around 4:30 am, with the two planets appearing about half a degree apart, similar to the width of the full moon. Observers noted that Venus will continue to move east of Jupiter over the next few weeks, making them visible together in the early morning sky. For those interested in future celestial events, resources like Sky and Telescope and astronomy magazines can provide updates. Some participants expressed disappointment at missing the event but found helpful tips for tracking similar occurrences. Overall, the conjunction sparked interest in planetary visibility and astronomy resources.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it?

Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with the moon being slightly less than .01 radians).

Awh I missed it :(
Where do you find out that things like this are going to happen?

I saw the two "stars" out my window in the morning about two weeks ago when they were somewhat further apart. I guessed it might be Venus and Jupiter, but googled it to verify.

They will still be fairly close together and visible in the early morning in the east before sunrise for the next couple of weeks. Venus will be moving east of Jupiter.

You can google "the planets for this month" and you would get links to things like Sky and Telescope magazine or astronomy magazine.

Oh, thanks! That's really helpful!

With Venus having a shorter period around the sun than Earth, with Earth having a much shorter period than Jupiter, Venus has now moved eastward and Jupiter westward, so that Jupiter now rises much earlier and Venus much later, with Jupiter now rising about two hours before Venus. This morning was very good viewing with the crescent moon between Jupiter and Venus to make it even more interesting. The moon will again be between Jupiter and Venus this coming morning (4-5 am or thereabouts). Jupiter rises in the east somewhere around 2-2:30 am.

Some 8 years ago I posted some experiments using 2 Software Defined Radios slaved to a common clock. The idea was measure small thermal noise by making correlation measurements between the IQ samples from each radio. This is a project that has kinda smoldered in the background where I've made progress in fits and starts. Since most (all?) RA signals are small thermal signals it seemed like the technique should be a natural approach. A recent thread discussing the feasibility of using SDRs to...

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
