Solve a mystery

TWAN brings you photos with mysteries. Share your thoughts with us and our global viewers. While some of the photos display a real mystery of unidentified object or phenomena, some others are already solved by TWAN team and appear here for educational purposes. TWAN post the explanation or the final conclusion at the month’s end. This program is a collaboration with Unidentified Aerospace Phenomena (UAP) international project.

               Mystery 3 : Streaks in Orion


TWAN Solve a Mystery

What are the streak at the right edge of this image near the belt of Orion? The streaks in the above image taken near Ankara, Turkey on 12 August 2007 would be identified at first glance as meteors from the Perseids meteor shower peaking just that night. Unexpectedly, however, these streaks do not point back to the Perseids radiant in Perseus (top center). Then what is their origin? The above image is a composite of several shots captured over the time span of 40 minutes. Other visible celestial icons include the V-figure of Taurus and the Pleiades star cluster, planet between them, bright star Capella near the center, and the rising stars of Gemini in the bottom center. Note the elongated light rising from the horizon toward the Taurus and passing through the winter Milky Way. This is the zodiacal light (sunlight reflection from dust in the solar system plane).

I really do not know what to say,but I do not agree with Tony L. An electric transmission wires that cross the entire field of view. They're really just stars, they have to be. Although my team and I are the best detectives around in (T) this mystery could be over all your heads,but not ours(J.k)!Now,here is a mystery for you. (What does T stand for?) Hint:It's a country

Tony L.

Electric transmission wires that cross the entire field of view. They are only visible where the light from the hill reflects off the metal, and are too thin to show up as dark streaks elsewhere. Note that the reflection is one circle, as would be expected from a single light source off a single reflective surface. Definitely NOT Iridium flares or meteors - too many streaks and too parallel.


Yes it may be some geostationary satellites. But the processing is realy tricky, the trees have not moved, that's impossible. It's a mix of a long exposure ofr the stars and a short one for the landscape. So it's quite hard to be sure, ...

It Might be the flares from geostationary satellites.The Geostationary satellites got totally eclipsed. They disappeared completely in the shadow of earth at about the same spot on the celestial sphere one after the other and cause this parallel streaks!

irridium Satellites

Deffinately sattelite. I am unsure of the name of them, but i believe them to be the French defence sattelites that are constantly in formation, and there are four of them. I have seen such a formation of four only once whilst stargazing (south west united kingdom) but i was easily able to cross reference what i saw with the Live 3D JAVA Tracking Display on the nasa website. ( Play about with it so you get real time updates and zoom in until you see a set of four tracks in a diamond formation, that will be them.

contrails are caused by the effect of the bright point in the lower right at the top of the hill on the lens of the camera?


Where's Mystery 4?

Alexander Prokofyev

One interesting observation. The 4 traces devide easely in two pairs: long and short traces. Let's count them from up to down. Then lets group them - the first group is (2,3) and the second is (1,4). Then it's still possible that at first there appeared the first group of satellites. And in 40 minutes after orbiting the Earth the same very satellites re-appeared again produsing traces of the second group. In this case they would lose some brightness (for the Sun is deeper under the horizon). And the increasing distanse between them gives birth to the next hypothesis: it's possible a separation of the ISS and a spaceship. To check the general hypothesis is easy: just to find out the details of ISS that very date, Aug, 12, 2007. The thin place in this explanation is 40 minutes. It seems to be very quick for ISS to reappear again.

The galactic highway of geostationary satellites cruising about their business some 20 thousand miles away from us! :D


This riddle har been thoroughly discussed in another site, after the photo was published as APOD. Almost every possible and impossible explanation was suggested. At the end, Iridium flares was the most probable one: the Ir satellites all have polar orbits, so they would pass where they are in the photo (that is roughly shot towards the east), and the location in the sky is consistent with the position of the sun below the horizon (which is reflected in their antennas). The problem was that, even though several specific Iridium satellite passages were listed, some doubt remained about how to match them with the times of the shots. The photographer himself participated in the discussion, which takes up four pages. See:

A rip in the space/time continunum.The 40min. time laps captures its opening to other world/universes.Angels zipping through rip of fabric from "our" time to enter "our" world. Then leaving cosmic trails to fad when "time" returns to our gravitational space!?!

Till Credner

At first glance like Iridium flares. But very unlikely to have four of the flares this parallel, even if there are many satellites in the same orbit. And there are more weak streaks above. My bet is an ordinary wire going through the field, which reflects the light of the distant mountain. Many recentered images yield the parallel streaks and let the dark streaks vanish from the single images.

Iridium flares.

Flaring satellites

mehdi momenzadeh

this image is not in very high quality, but we can see at least four streaks.the second and fourth are so much like iridium flares with high magnitudes. the first also can be iridium flare or reflection by another sattelite. but the third is more complicated. is it an iridium flare, and camera exposure terminated just in its center of flare? if they are just sattelite flares they can be easily examined by knowing the exact time of exposures and flybys.

Mohammad Ashrafy

I think we have three theory ,I agree with Mr.Aghaei 's two theories ,But we shouldn't forget lens flare and noises.It also can be Iridum flare.


Yes I agree,it could be due something related to the camera,they do not look like anything and they are absolutely parallel to each other,a glassy part during exposure has reflected some light from somewhere onto the sensor.


Possibly a reflection on the inside lens of the camera?

Pete Ferguson

I believe those streaks are an anomaly created inside the camera. They are being caused by the bright light at the top of the hill on the right side of the photo. I recently took a photo of my dog in front of a sunset, with the sun just peaking into the side of the shot, and I obtained red streaks like that in front of the dog. Not as exciting as a UFO or an exploding satellite. Sorry. (Alternative explanation: satellites catching the sun. Last night, August 10, I observed a satellite at about 10:00 pm, at Latitude 45 degrees, get extremely bright for a few seconds almost directly overhead as it caught the sun while passing in a south to north direction. This would require 4 satellites passing the photographer's location in 40 minutes.)


I remember that I have seen such bright flares in summer Perseus At first one might think it's either Iridium satellites, which in this case it's pretty rare since there is a number of them moving at the same location and direction. Satellites are usually dispersed in space. Meteor showers are mostly a big cloud of particles, all hitting the atmosphere in one direction. Therefore I agree with Mr. Ali Aghaee's first hypthesis.


Yep! I agree! Iridium flares.

Mohammad Saber Ali Aghaei

One hypothesis is that the streaks are part of a microburst from a much less active meteor shower known as the Alpha Ursae Majorids. Another possibility is that they are parts of a satellite that broke up as it re-entered the Earth's atmosphere.
