Quadrantid meteor in 2016, caught just as the clouds were closing in, by Deb Kestler in Middletown, Rhode Island.
Although the Quadrantids can produce over 100 meteors per hour, the sharp peak of this shower tends to last only a few hours, and doesn’t always come at an opportune time.

This meteor shower has a relatively broad maximum – meaning you can watch it the day before and after the predicted peak of May 6.
Like the Eta Aquarids in May, the Delta Aquarid meteor shower in July favors the Southern Hemisphere and tropical latitudes in the Northern Hemisphere. Composite image of the Perseid meteor shower in 2013, by Scott MacNeill at Frosty Drew Observatory in Charlestown, Rhode Island.
The Perseid meteor shower is perhaps the most beloved meteor shower of the year for the Northern Hemisphere, and the 2016 prediction for an outburst should have many watching this year’s shower on the night of August 11-12. The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. On a dark, moonless night, the Orionids exhibit a maximum of about 10 to 20 meteors per hour.
The meteoroid streams that feed the South (and North) Taurids are very spread out and diffuse. Like the South Taurids, the North Taurids meteor shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour. Radiating from near the bright stars Castor and Pollux in the constellation Gemini the Twins, the Geminid meteor shower is one of the finest meteors showers visible in either the Northern or the Southern Hemisphere.
This Geminid meteor is seen coming straight from its radiant point, which is near the two brightest stars in Gemini, Castor and Pollux.
Bottom line: 2016 will be a great year for watching meteors in late July and early August.

We celebrate the New Year not only for the food and the fireworks, but because on this day we celebrate love, family and fun.

Author SpotlightAnnako Hello, I’m Annako – a travel nerd, web buff wannabe, passionate blogger next door and a coffee addict. But these were just the worlds around our Sun, which houses (according to current definition) eight planets. We may think of our Sun as being typical and on the relatively dim side, since a disproportionate number of stars visible to our eyes in the night sky are O, B, and A-class stars. And the transit method, where the light coming from a distant star is partially blocked by the disk of a planet in its solar system passing in front of it. It’s important to recognize, when we do this, that we will not see the vast majority of planets that are out there. Now you may think those are not-so-good odds, but you don’t even know the half of it.
So this means that if Kepler were looking at 100,000 stars identical to our own, it would have found 410 stars with a total of 700 planets around them. But as of today, Kepler has found over 11,000 stars with at least one planetary candidate, and over 18,000 potential planets around those stars, with periods ranging from 12 hours up to 525 days. In other words, based on what we’ve seen so far, most stars are likely to have planets, and based on what we’ve seen in the inner solar systems of the ones that do, a large fraction of them are likely to have more rocky planets in their inner solar systems than even our own has, to say nothing of the outer solar system! With at least 200 billion galaxies out there (and possibly even more), we’re very likely talking about a Universe filled with around 1024 planets, or, for those of you who like it written out, around 1,000,000,000,000,000,000,000,000 planets in our observable Universe.
However, I sometimes wonder if the irony might be that we live in a universe (potentially filled with life) that can’t ever be visited by any member of that universe just due to the laws of physics of that universe.
3) number of stars in the observable universe – the beach would be 333,333,333 Km long.
Until recently I had imagined that the stellar wobble method for finding exoplanets would involve measuring the visible change in a star’s position as viewed from the earth, for example right-to-left and back again. I don’t think anything has ever fired up my imagination the way the search for exoplanets does!
So , using doppler shift, if we are looking directly in the plane of the solar system, we will see a particular red shift. Now in the intermediate case, say 45 degrees, the redshift will be present, but half of what you would expect in the edge on case. Now – here is my question – since the degree of redshift depends on the angle at which we view it, how is it possible to correct for this when trying to calculate the mass of the planet? Also, in the pure situation of one large planet, the redshift method is clear, but let’s say there are 4 large planets. Phil as I understand it when there are more planets you have to decompose the complex curve into its constituent parts, much as you decompose a soundwave into its constituent (pure sinusoidal) partials, by e.g. Even if only 0.000001% of 150 billion have life on them, that’s still 15000 planets with life in our milky way!
Ethan, based on these numbers, what would be the latest value (estimate) of the Drake equation? One point we all seem to be missing is the huge uncertainty in one element of the drake equation (an equation that lays out the factors that multiplied together determine the probable number of detectable extraterrestrial civilisations out there).


First of all, the only theoretical speed limit we’re aware of is that of the speed of light.
In short the idea is to provide constant acceleration by the help of the interstellar medium. With relativistic speed (in respect to the rest of the material universe) one will encounter with time dilation which in turn would resolve the problem of reaching vast distances within reasonable time. Thanks, that’s what I believed in the usual cases but I wondered how it worked for a system whose star we view from one of its poles. It’s too bad that the same systems that are best suited for Doppler methods are also the ones most likely to involve transits. Have you ever come across someone’s knowledgeable power spectrum estimate of masses in our galaxy, from blue giant to brown dwarf to super-Jupiter to dwarf planet? It does no good for a meet-and-greet with alien lifeforms if they already passed through our neck of the galactic woods hundreds of millions of years ago.
It would be much more logical for it to be powered by astronaut piss than interstellar hydrogen.
Plug this into the Drake equation, and all you can get so far is that the answer might still possibly be non-zero. Unfortunately, in 2016, the full moon almost exactly coincides with the peak of the Lyrid meteor shower. This shower favors the Southern Hemisphere, and is often the Southern hemisphere’s best meteor shower of the year.
On that night, if the outburst occurs for you, and if the moon is down and the radiant point is high when it occurs, you might see 200 meteors per hour.
But, in 2016, the waning gibbous moon will be out during the morning hours before sunrise, when the Orionid meteors fall most abundantly. That means the Taurids are extremely long-lasting (September 25 to November 25) but usually don’t offer more than about 7 meteors per hour.
You can comfortably watch meteors from many places, assuming you have a dark sky: a rural back yard or deck, the hood of your car, the side of a road. Well, in planning my night photoshoots I use a variety of apps and web pages to know how dark the sky is in a certain location, the weather forecast, and how the night sky will look. I’ve learned the hard way that, now matter how perfectly dark the sky is at your location, it won’t matter if there’s a layer of clouds between you an the stars. Although astronomers have tried to publish exact predictions in recent years, meteor showers remain notoriously unpredictable. He's a sundial aficionado, whose love for the heavens has taken him to Lake Titicaca in Bolivia and sailing in the North Atlantic, where he earned his celestial navigation certificate through the School of Ocean Sailing and Navigation. More than anything else, it is the time we spend together with our loved ones that make this day more blessed and meaningful. The rocky planets, our four gas giants, and the moons, asteroids, comets, and kuiper belt objects (which was only Pluto and Charon at the time) were all that we knew of. Our Sun is just one of an estimated two-to-four hundred billion stars in our Milky Way galaxy, and looking up towards the night sky, one can’t help but wonder how many of those stars have planets of their own, and what those worlds are like.
But in reality, the Sun is more massive and intrinsically brighter than 95% of stars in our galaxy.
Take NASA’s Kepler Mission, for instance, which has discovered hundreds (if not thousands) of planets by looking at a field-of-view containing around 100,000 stars.
But regardless of which way it goes, we’re talking about trillions of planets in our galaxy alone. I was thinking of the # of grains of sand on a beach compared to the # stars, galaxies, etc. I would quite happily die tomorrow if I could spend the time until then poring over a photo album of gorgeous, strange scenes from other planets in our galaxy. And it seems, after a little more searching online, that there are methods for finding a star’s rotational velocity and direction.
Imagine a very long equilateral triangle with the earth at the skinny part and the other two corners the extreme points of the star’s apparent excursion. The reality, without FTL travel, is that you leave one planet to colonise another and never heard from again.
Civs 2+ will be so far behind (odds of similar tech levels meeting are tiny), that the oldest will be galaxy-spanning before the second one gets off its planet.
The really big unkown is fl – the fraction of potentially habitable planets that go on to develop life.
Actually, the laws of physics does allow to reach many of the surrounding worlds, even to the point, that there’s the theoretical possibility to coast around a good bit of the observable universe.
While the interstellar medium is scarce, as the spacecraft gains relativistic speed, the collection rate would increase.
In that case there is a tiny Doppler effect, since as the star appears to wiggle from side to side it must also change its distance from us (I think this is what Wow meant), but my back-of-the-envelope makes the effect much too small to do the job.
Much more hydrogen atoms in one cup of piss than any that can be scooped up by a ship from the vacuum of space.
With so many planets out there, the odds pretty good that at least some of them are hospitable at least for extremophile bacteria or things like those. About 10 to 15 meteors per hour can be expected around the shower’s peak on a dark, moonless night. More meteors tend to fly after midnight, and the Orionids are typically at their best in the wee hours before dawn. Meteor showers occur over a range of dates, because they stem from Earth’s own movement through space. Your best bet is to go outside at the times we suggest, and plan to spend at least an hour, if not a whole night, reclining comfortably while looking up at the sky.

As the New Year rings in, our lives take a new, more positive point of perspective, making us hopeful for the days ahead—and along the way, a better person than we were days before. But just for fun, that’d give us somewhere around two-to-three trillion planets in our galaxy. With all of those chances, we’re bound to get lucky if we persevere and look hard enough! When the star is at the center of its motion, forming a right-angled triangle with the earth and either extreme, a little trigonometry will give the difference in length between the two long sides. We certainly have come a long way since 1813 the steam locomotive was only spanking new invention just about the change our idea of mass transport. As you get closer and closer to the speed of light of course, the time dilation will cut you off from the human race on earth or even in the solar system because the time dilation gets so high that perhaps no one will be alive by the time you decelerate and come to rest in respect to you destination star system. Lyrid meteors tend to be bright and often leave trails, so maybe a meteor or two might overcome the drenching light of the full moon in 2016. The radiant is near the star Eta in the constellation Aquarius the Water Bearer (click here for chart).
The Taurids are, however, well known for having a high percentage of fireballs, or exceptionally bright meteors. It’s a website that shows the light pollution in and around cities in North America which has been fundamental for finding dark sites to setup shots.

With the coming of the New Year comes the promise of a more prosperous and gracious future. And as we know from our own Solar System, there’s a great variety of what the surfaces of those planets could look like. Consider the following: if Kepler were looking at our Solar System, and our Solar System was oriented randomly with respect to our perspective, these are the odds that the alignment would be good enough to observe a transit of our star by one of our planets. It could be close to unity, or on the other hand it could sit at the ten to the power minus 100 and above level. The combination of these three contingencies might be so rare as to still assure that we are alone. Watch for Perseid meteors on the nights leading up to the shower, too, even as early as early August. The zenithal hourly rate for the Geminids is up to 120 meteors per hour, after some good displays in recent years.
Dark Sky finder also has an app for iPhone and iPad which as of this writting is only 99 cents so you might want to look into that as well.
Be sure to dress warmly enough, even in spring or summer, especially in the hours before dawn.

Tomorrowland Pull some high"Gs"on the Space mountain high-speed rocket ride, or pilot a spaceship amid spinning planets on Orbitron!
We don’t know because we are still pretty much in the dark about how the first life evolved on our planet. There is nothing in the laws that prevents us from building a spaceship powered by a black hole or bad news for that matter. Perseid meteors tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. When this cometary debris enters our atmosphere, it vaporizes due to friction with the air. For people not in North America, the Blue Marble Navigator might be able to help to see how bright are the lights near you.
Until we have a good understanding of that we will simply be guessing wildly at this key number. If moonlight or city lights don’t obscure the view, we on Earth see the falling, vaporizing particles as meteors.
In 2016, the full moon will be out all night long, subduing the usually prolific Geminid meteor shower on the night of December 13-24. We must simply admit that based on planet numbers etc at this moment we have no idea if there is likely to be life out there. In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour.
A waxing gibbous moon will be interfering with the show, but it’ll be gone from the sky by the predawn hours.
