What planets are visible tonight?

Which planets are visible depends on your date and location. Venus, Jupiter, Mars, and Saturn are the four naked-eye planets that are frequently visible; Mercury is visible only in brief windows near sunrise or sunset. Enter your city above and the report will list the planets currently above the horizon after dark.

Can I see the Northern Lights tonight?

Aurora visibility depends on the Kp index and your geomagnetic latitude. At Kp 3, aurora is typically visible only near the Arctic and Antarctic circles. At Kp 5 (a G1 storm), the auroral oval expands south into the northern U.S. and northern Europe. At Kp 7+ it can reach mid-latitudes. The report above compares your latitude to the current auroral boundary in real time.

Is there a meteor shower tonight?

There are around a dozen major meteor showers each year. The report above shows the next active shower and how many days until its peak. For best viewing, look after midnight from a dark location with the shower's radiant above the horizon.

When will the ISS pass over tonight?

The International Space Station passes overhead multiple times per day, but only some passes are visible (bright, after dusk or before dawn, and above the horizon). The report above shows the next visible pass time for your location, computed from live NORAD orbital elements.

What can I see in the sky tonight from Boa Vista do Gurupi, Maranhão, Brazil?

Can I see both northern and southern constellations from Boa Vista do Gurupi, Maranhão, Brazil?

Yes — this is the real advantage of an equatorial location. At 1.8° S, about 51.6% of the entire celestial sphere rises at some point in the year, so Polaris-side constellations and the Southern Cross region are both reachable across the seasons.

How good is the Milky Way from Boa Vista do Gurupi, Maranhão, Brazil?

The Galactic Centre culminates around 62.8° above the horizon from here, high enough to clear most horizon haze. Local cloud and humidity, not geometry, are usually the limiting factor at tropical latitudes.

Are there seasons for stargazing in Boa Vista do Gurupi, Maranhão, Brazil?

Night length barely changes at this latitude — twilight is short and the Sun sets steeply, so darkness arrives quickly all year. What changes is which part of the sky is on view after sunset, and, in monsoon-affected regions, how often the sky is clear at all.

How dark does it actually get in Boa Vista do Gurupi, Maranhão, Brazil tonight?

About 9.6 hours of astronomical darkness (Sun more than 18° below the horizon). That is the real observing window for faint objects; brighter targets are workable from dusk onward.
